Worrying message " ata4: EH pending after 5 tries, giving up" from dmesg

Bug Description

In 64bit intrepid I find the following messages repeatedly appearing in the kernel ring buffer "ata4: EH pending after 5 tries, giving up" and "ata4: EH complete". The "ata4: EH pending after 5 tries, giving up" message seems to appear during periods of hard disk activity

SRU Justification

Justification: warning messages may flood the syslog following a suspend

Impact: warnings flood the syslog in response to disk activity

Fix Description: ensure the driver ports are thawed following suspend

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commit;h=d0d9905864bb51e89f50f73b7aedb4df45d7663a

Risks: this is a driver specific change

TEST CASE: see bug

I notice that I do not get these messages when using linux 2.6.27-2-generic.

I get them on i386 too (amd64 processor) so they are not 64bit only

I get them here as well. AMD64, 2.6.27-3, I did not see them prior to updating to this kernel from 2.6.27-2.

Can also confirm bug. i386 2.6.27-3, renders my phone unable to connect through USB. Did not have this problem in Hardy.

Arch linux has worked out what the problem is, see here: http://bugs.archlinux.org/task/11535

got the same problem on a amd32 box after installing intrepid alpha 6. cannot seem to be able to update, everytime I try to write the code 'apt-get update/grade" the error mesages flare up.

I have verified this bug using an unpatched mainline linux-2.6 kernel, found the commit causing trouble, and reported the bug upstream.

small correction, I am able to input codes and update, (though that did not solve any problems yet) the bug prints the error message while typing, but it does not interfere with the command itself. Now we play the waiting game.

2.6.27-4-generic did *not* fix the problem

I think this is a xorg related problem, at this point the computer does boot normally, exacept at the GDM screen the monitor turns itself off.

it is still possible to do "CTRL+ALT+F1" to access terminal, there I can at least try to update (successfuly so) where the message above keeps being printed.

I tried using the recovery boot to do a xfix or fix any broken packages, but that doesn't help.

Something was displayed when I tried to copy the xorg.conf of my hardy partition and substituted it into the intrepid one. The X cursor appeared and a dialogue saying that it could not load drivers came up.It asks if I wanted to fix it which I am given the options to reconfigure or to edit the xorg.conf file. None of the options seem to make any difference. Upon restart the same old problem resumes.

I am on a 32bit box with a radeon video card

According to the discussion on Arch it's a sata_nv.patch that came into the kernel that causes this.

It's anoying as hell.

waspbr:
No, this bug has nothing what so ever to do with Xorg, you should report a separate bug for your xorg problems.

Mårten:
Yes, it was a change in sata_nv that caused the problem. To be more specific it was commit 2fd673ecf0378ddeeeb87b3605e50212e0c0ddc6, as I wrote in my upstream bug report.

For those not following the upstream bug, Tejun Heo have found and fixed the problem. His patch is included in the newly released 2.6.27-rc8, which means that as soon as Ubuntus kernel is rebased on rc8 we will get the fix.

problem still exists in intrepid beta (64bit) from 3rd october

Don't worry, the fix is coming any minute now :)

The new Linux kernel has the fix, it is in the queue, at seems like it was approved to be uploaded in main. Just check Update Manager tonight, they should be there.

To keep you updated, check the freshly uploaded at:
https://launchpad.net/ubuntu/intrepid

bug fixed in 2.6.27-5

I have a similar problem, can it be that sata_via has the same bug?
Thanks!

This is back again!!!

Re-opening as per last comment.

The bug was reopened upstream and fixed by kernel developers http://bugzilla.kernel.org/show_bug.cgi?id=11615

Please pick up the new patch: libata-thaw-after-reset-skip.patch

Thanks,
Dan.

This patch is the one attached.

I have picked up this patch and applied it to the latest Intrepid kernel. If those of you who are affected by this issue could test these kernels and report back here that would be helpful. The kernels are at the URL below:

http://people.ubuntu.com/~apw/lp269652-intrepid/

Andy, I know that this bug was fixed for Intrepid 2.6.27 as of version 2.6.27-5 (around 6th of October 2008).
I don't think that it resurfaced in 2.6.27 (Intrepid) (I don't know, I moved to Jaunty).

My message refers to 2.6.28 (Jaunty). It seems that new stuff was introduced in 2.6.28 for nForce 2/3 chipsets which made the fixed bug reappear. From the patch explanation, by Tejun:

"This problem has always been there but is uncovered by recent sata_nv
nf2/3 change which dropped hardreset support while maintaining SCR
access."

I will gladly test an updated 2.6.28 Ubuntu kernel. I already tested vanilla 2.6.28 on the kernel's Bugzilla and Tejun's patch fixed the problem. By the way, it was vanilla, but compiled with Ubuntu's kernel config file.

It was not fixed for me and I still have to use a custom built kernel using .config from debian.

I will try to test suggested packages later today.

im also having this problem on jaunty kernel 2.6.28

Ok I have now built some test kernels for Jaunty as well (the intrepid kernels are unchanged).
If those of you who are affected by this issue could test these kernels and report back here that would be helpful. Please report which kernel you tested. The kernels are at the URLs below:

Seems to be working now, must have been syncing still.

Andy, I can no longer see the worrying message with your updated kernel for Jaunty.

Many thanks.

the messages are gone for now ( andy's amd64 jaunty kernel )

kulight, you are right, I should have specified the architecture: i386

so both i386 and amd64 are tested, message disappeared

i hope this is not the package that will be released and its only for testing because now i get gui crashes

Hi Andy, the fix did not work for me on intrepid 32 bit. I am still getting:

Sorry, I did not intend to write that thing.

I was notified that the fix was added in the queue for the mainline kernel, 2.6.27 and 2.6.28.
So, at the next kernel update from kernel.org, the fix should be in.

Andy, just monitor the bug, no need to do anything now.

one more kernel upgrade and the bug is still here

desktop:~$ uname -a
Linux kulight-desktop 2.6.28-10-generic #32-Ubuntu SMP Mon Mar 16 02:48:55 UTC 2009 x86_64 GNU/Linux

It will disappear after the official kernel upgrade (at kernel.org). Now, it is at 2.6.28.7 released on 20th of February.
Ubuntu kernel is based on this 2.6.28.7 (the fact that it is called 2.6.28-10 does not matter)

There is no need to patch it now, since the official update will fix the bug anyway and it will appear in time for Jaunty.
Otherwise, if the official kernel is not updated in time, I'm pretty sure that Andy will patch the Ubuntu's kernel.

I'm getting this error on boot and it is rendering my two SATA drives unusable. The system still boots and runs off of the PATA disk. I'm running 9.04 and my kernel is up-to-date. I've seen this get fixed and opened and fixed and opened and I was wondering what it would take to re-open it.

No, this bug did not cause any hard resets of the sata link or any
SStatus 100, SControl 300 errors. It only flooded this type of messages:

ata4: EH complete
ata4: EH pending after 5 tries, giving up

This means that you have another problem and should open another bug.

Oh, my apologies. I didn't realize that the additional messages would mean that it was a different bug. I'll file a new report. Thanks!
