Bug Description

Using any kernel later than the one that I wrote this report with, whenever wifi associates with a station GNOME freezes and you have to power cycle.

Which specific kernel versions did you test? I figure 2.6.32-32.62 is broken - have you tried 2.6.32-33.68, currently sitting in -proposed (https://wiki.ubuntu.com/Testing/EnableProposed)?

@Julian - I'll enable -proposed and check. This is my personal workstation and hard to experiment on during the day because of my 'real' job :) Needs to be stable & dependable.

@Julian - ok had time to enable the -proposed repos and update. Good news, seems to work! Will connect now and not cause GNOME to hang. Gets my vote!

I did get a freeze up today, but wow will it be hard to figure out.
VPN was active
VMWare Windows XP session up
practically all 8Gb in use

tried to switch to different wifi network, GNOME froze the instant it associated.

couldn't duplicate it again. :(

Alright - there's a known regression affecting only pae-kernels, where 2.6.32-31.61 is good and 2.6.32-32.62 is bad (see bug #805209).
You said that "any kernel later" than 2.6.32-30.59 is causing this problem - was 2.6.32-31.61 part of your tests?

@Julian - it's a challenge because I probably didn't test every single one of them. I ran every PAE kernel from 59 that was in -stable and saw the lockup issue. Following the suggestion to enable -proposed I am running 69. Haven't tried any others at this point. A quick look at my grub2 config lists these.

I'm pretty sure I tried each PAE to find one that wouldn't lock up. The 'best' one was the one I used to write the bug with. I can try rebooting 31.61 to be sure if you would like me to.

Well, testing whether this can be reproduced on 31.61 (or for that matter, any non-pae kernel) would definitely help in isolating the issue.
There's no reason to continue using 33.69 from -proposed, now that you determined it's still broken.

Hi Julian, booted 31.61 PAE and seems to be holding so far. 33.69 PAE worked for a long time and then seemed to lock up once I've used VMWare with a huge image and then closed it.

I'll try 31.61 non-PAE later this evening.

I'll keep running 31.61 PAE for a bit & post if it croaks.

Came in this morning and the system was locked up. Worked great from the time I posted until I left for the night. Here's the last bit in the 'messages' file from the 11th. Most of the other messages are firewall messages about 1x / 10sec.

Booted latest kernel as discussed in bug #805209. Seems to associate without hanging up. Will let it run overnight to see how it goes.

Seems to be working, stayed up overnight without lockup. I'm going to mark as duplicate of bug #805209, change if you disagree.
