Ralink rt73 hangs and requires reboot

Bug Description

My rt73 based DLink DWA-110 USB stick had no problem under Hardy 2.6.24-19, so this seems to be a regression.

The connection initially works fine. However, under load the connection locks up - the system tray icon shows signal but there is no network traffic going in or out. Running sudo /etc/dbus-1/event.d/25NetworkManager restart restarts network manager but the connection will no longer connect to the network. Rebooting the machine gets me connected again.

This is easily reproducible - I just need to fire up a Bittorrent client for a few minutes.

===

SRU Justification

Impact: high network load leads to loss of connectivity, a reboot is required to recover

Fix Description: switches to former atomic operations

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commit;h=a52e017788f9ab062372bf1a27107101ad46e733

Risks: this is a driver specific change

TEST CASE: see bug report

I can no longer reproduce this with 2.6.24-21.40

Spoke too soon - it is still happening. Just took longer to trigger.

I noticed that if I restart network manager after the hang (/etc/dbus-1/event.d/25NetworkManager restart), the wireless networks will still be seen but cannot be connected too (in the panel icon both circles stay blue while the swirly thing swirls for a bit, where as the bottom circle is normally green).

The same problem occurs with me! :(

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Why was this flagged incomplete? The issue for Hardy is still there, and all information asked for Hardy has been provided. If it works under 2.6.27 is irrelevant unless Hardy is switching from 2.6.26.

Hi Stuart,

We really appreciate all the information and testing you've provided already. However, according to SRU Policy we need to verify this issue is first resolved in the current development release before a backport for Hardy can be considered - https://wiki.ubuntu.com/StableReleaseUpdates . If this is not resolved for Intrepid a fix will need to be applied to Intrepid first and then backported to Hardy. Or, it could be that this is already resolved for Intrepid which can then help narrow down the possible patch to backport for Hardy.

There has also been some discussion of providing a newer kernel for Hardy so any feedback you can give us will help with making that assessment.

Also I'm curious if rather than rebooting in order to reconnect, what if you just unload and reload the module? Thanks.

Subscribing the SRU team, as this looks to be a regression in the proposed 2.6.24-21 update.

Tim, this is a regression in the current hardy-proposed SRU. Can you please take a look at this? Thanks!

@Stuart - The rt73 USB driver has not changed since November 2007 in the main kernel sources. Do you have linux-backports-modules installed? There is an updated driver in that package that may work better.

@Martin - I do not think this is a regression. The rt73 driver was barely functional from the very beginning.

@Tim - Yes, I have linux-backports-modules installed, as does everyone else using Ralink cards in Hardy (?) because Bug 134660 did not get resolved in time for Hardy release. Should this be targetted at linux-backports-modules instead?

I have the same problem using Ubuntu 8.10 beta 1, with a Ralink PCI card and a RT73USB driver.

The connection breaks after some times of internet uses. It depends of the quantity of data you exchange : if you do a ftp with a 1.3 Mo/s rate it will break sooner.

I'm a using a 2.6.27-4-generic kernel.

I have tried with other linux distributions, and I had the same problem.

With a Mandriva I have dumped those lines in messages log :

*Sep 20 20:10:04 localhost kernel: phy0 -> rt2x00queue_write_tx_frame: Error -
Arrived at non-free entry in the non-full queue 2.
Sep 20 20:10:04 localhost kernel: Please file bug report to
http://rt2x00.serialmonkey.com.*

It seems to be a regression in the kernel :

http://groups.google.com/group/linux.kernel/browse_thread/thread/189864466d6ed5f4/5189422969b027b8?lnk=raot

I have some more traces with this newer 2.6.27 kernel in the messages log. When RT73 hangs everything seems to work but the connection (network manager indicates an alive connection) is broken. I have to desactivate it and to connect again.

Marking the Hardy task for the linux package as invalid and adding the linux-backports-modules-2.6.24 package to the bug, based on Stuart Bishop's comment.

Stuart, Rodrigo:can you confirm that you are seeing this problem with linux-backports-modules 2.6.24-21.27 installed, as released in hardy updates?

Nicolas: are you still seeing this in the latest Intrepid kernels?

Leann: do you think it would be best if Nicolas reported his problem with 2.6.27 in a separate bug?

Thankyou all for your patience in tracking down this bug.

I have the some problem after the kernel upgrade to 2.6.24.21 :-(

My rt73 based DLink DWA-110 USB stick had no problem under 2.6.24-19.

I hope in some solution, plese.

Hi Steve,
With an upgrade from today and the last kernel I still see this behaviour
with the RT73usb module.

I have seen in the Ubuntu bug list today a new opened bug about this same
problem on Intrepid.

This new bug description is showing interesting messages log (that I could
see while I was using Mandriva 2009 but that I could not find in Ubuntu).

You have asked Leann if I should separate my problem from the existing one
but someone else has already done that !

This new bug is there :

Nicolas, thanks for your comment and the pointer to bug 283759; people who are having trouble this hardware under Intrepid should follow that bug. Closing out that portion of this bug.

Ok but it seems to be very related. Could you tell me if this new bug will
be taken in charge by the Ubuntu team ?

I'm reconfirming this. This is still a regression bug in Hardy, and Hardy is still supported. The last known good release is the 2.6.19 package which we can thankfully still boot too.

I'm seeing identical behavior after upgrading to Intrepid with the linux-backports-modules removed (the device is not detected at all with linux-backports-modules installed).

Some possibly relevant messages:

Dec 7 13:50:10 aargh kernel: [14538.952593] phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2.
Dec 7 13:50:10 aargh kernel: [14538.952595] Please file bug report to http://rt2x00.serialmonkey.com.

The Mandriva bug lists the same error message and same behavior.

http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=5&t=5006&start=0&st=0&sk=t&sd=a constains the upstream bug report from two months ago but it hasn't been gardened into their bug tracker yet.

@Stuart Bishop -- it is quite possible your bug is related to the bug fixed in the commit below, in the upstream wireless tree. It does not yet appear to be merged into mainline, not sure when that will occur as yet.

http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=9fe32736d2cf27dfbf25cb7536c4358cd0dab6de

The patch which Andy referenced is available in the kernel for the latest pre-release of Jaunty 9.04 (currently Alpha 5) - http://cdimage.ubuntu.com/releases/jaunty/ . It contains a 2.6.28 based kernel. It would be great if someone could test with the latest Jaunty Alpha 5 LiveCD and confirm if this issue remains. Below is the jaunty git commit for this patch. Please let us know your results.

rt2x00: Fix race conditions in flag handling

@Stuart Bishop -- I have pulled this patch back to Intrepid and built some test kernels. If you could test those kernels and report back here that would help us justify an SRU for Intrepid. The kernels are at the URL below:

http://people.ubuntu.com/~apw/lp258985-intrepid/

@Andy -- Would it be possible to have a patched kernel for the hardy heron also? I would be pleased to test it.

@Aspora, for Hardy there is little chance to get this into the driver (the code base is just too different). There is a chance that linux-backports-modules works (though the driver there is not at the same stage as in intrepid). I prepared LBM packages for the latest proposed version of the Hardy kernel. Should you need them for the updates version, please let me know. The packages can be found at http://people.ubuntu.com/~smb/bug258985/

@Andy - No dropouts, decent signal and decent speeds for about 8 hours so far. Looks good from this end.

Still no dropouts or other problems. Please consider this for SRU.

Closing the development task for l-b-m-2.6.24.

The fix for this issue is already fixed in Jaunty kernels.

Accepted linux-backports-modules-2.6.24 into hardy-proposed; please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I installed the proposed module and after 10 days the bug seems to be fixed: until now no more reboots were needed... Thanks!!

This bug was fixed in the package linux-backports-modules-2.6.24 - 2.6.24-24.32

Hi,

For the last couple of months I've been plugged to the cable because I haven't had the chance to continue to test the fixes proposed for this bug. Finally I was able to make some time and I've tested it, unfortunately my desktop-PC still hangs as soon as the module is loaded. I'm using Jaunty so the only thing I had to do is to remove the module from the blacklist.conf file.

I tried it with and without using NetworkManager
