This problem manifests itself when resuming from RAM, but only very infrequently. This is the third occurrence since I started using this machine three months ago. I suspend it to RAM at least twice a day. The previous two occurrences were on 3.0. So not a clear regression in that sense. (Note this is from memory, I didn't record those other two oopses)
However, since it happens immediately upon resume, I suspected it was related. Would you have any tips for stress testing resumes? If I can increase the reproducibility then I could try to bisect it.
Or do you think it better, judging from the back trace, to forward this to some other subsystem maintainer? Please do then, I obviously don't know how to read backtraces.
Thanks,
Wouter
