2.6.19-rc[123]: Oops in __wake_up_common during htc magician resume.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi!

When I switched from 2.6.18 to 2.6.19-rc1 processes started to get killed
during resume due to an oops in __wake_up_common on my arm
pxa272 device (htc magician). The patches I used are at
http://userpage.fu-berlin.de/~zabel/magician/magician-patches-2.6.19-rc3-20061025.tar.bz2

Is there any information in those reports that could help me find the issue?
I have no idea how to debug this, so I'd appreciate any hint.
