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.
Ooops in comment 1 is same issue as bug 233364, fwiw...I don't think it relates to the original report in this bug. Is this still happening with current rawhide kernels? There have been several mac80211 and iwlwifi updates in the meantime... 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. 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. 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. |
