I think this report is new. If it is a duplicate, I apologize for any noise.
My kernel is from wireless-testing. A 'uname -r' commands yields
2.6.26-rc2-wl-07884-g5d3790d-dirty. It is "dirty" due to some trial patches
in the b43 driver that should not have any effect on this oops. The computer
is running the x86_64 version of openSUSE 10.3, and I have not seen this oops
before.
The system was last booted at 18:02 on May 15. Until 10:10:58, everything
seemed normal. Then a reason 3 deauthentication arrived, and the following
ensued:
May 16 10:10:58 larrylap kernel: eth1: deauthenticate(reason=3)
