[dell-xps-specific?] ipw3945: Wireless is not activated after waking up from resume with kill switch enabled

Bug Description

I need to manually right-click on nm-applet and de-check wireless and check it again, only then will the wireless LED light up and the wireless features start working again. Once I got a kernel panic while doing this, so I am not too fond of that work-around.

This is NOT a duplicate of bug #193970 - this handles this specific case and was opened by the suggestion of others in that bug's comments.

Adding hal to affected packages since it seems wrong for the killswitch detection scripts to rely on /usr/lib/hal/hal-system-smbios --st_wwan for dell laptops when that command always returns 0:

motin@motin-xps:~$ sudo /usr/lib/hal/hal-system-smbios --st_wwan ; echo
0
motin@motin-xps:~$ # turning off switch - wireless on
motin@motin-xps:~$ sudo /usr/lib/hal/hal-system-smbios --st_wwan ; echo
0
motin@motin-xps:~$ # turning on switch - wireless off
motin@motin-xps:~$ sudo /usr/lib/hal/hal-system-smbios --st_wwan ; echo
0

A typo is fixed in the script: Bug #368553

An alternative work-around is to disable+enable the killswitch, then the wireless is detected again.

Hi Motin,

Can you try installing linux-backports-modules-jaunty to see if it helps, it contains and updated compat-wireless stack. If the issue remains, can you attach your dmesg output after a suspend/resume cycle but before you do one of your workarounds? Could you also try the latest compat-wireless stack to see if it also helps? http://wireless.kernel.org/en/users/Download . Thanks.
