Comment 1 Richard Hughes 2007-03-23 17:39:35 UTC 
Created attachment 150777 [details]
oops output due to null dereference

Got the attached NULL pointer dereference this morning just from booting. Hard
hang, numlock was just flashing. This is with 2.6.20-1.3016.fc7.
Comment 2 John W. Linville 2007-03-23 18:00:44 UTC 
Ooops in comment 1 is same issue as bug 233364, fwiw...I don't think it 
relates to the original report in this bug.
Comment 3 John W. Linville 2007-04-20 18:06:30 UTC 
Is this still happening with current rawhide kernels?  There have been several 
mac80211 and iwlwifi updates in the meantime...
Comment 4 Richard Hughes 2007-05-11 16:15:52 UTC 
No segfault, although it now does do something odd with my interrupts, causing
my mouse to loose sinc every 20~ seconds and my keyboard to go odd on shutdown.
If I remove the module then everything is okay, so I'm pretty sure its iwl3945.
Comment 5 John W. Linville 2007-05-14 21:25:03 UTC 
Others are seeing the keyboard issue as well, but I haven't seen a bug 
opened -- would you mind doing that?

I'm going to close this one since the keyboard problem is a separate issue.
Comment 6 Richard Hughes 2007-05-17 11:08:00 UTC 
John, I've switched to a x60 for the foreseeable future, although I can still
test stuff on my n100 if you need me to. On the x60 the iwl3945 driver work
flawlessly, except with suspend/resume, but that's a seporate issue.
