Beware, this might well be a TuxOnIce bug, but the backtrace looks quite
general so I am reporting it here. I set Nigel Cunningham on Cc, so he can
comment too.

Last kernel and tuxonice-Version that worked:
2.6.34.1-tp23-toi-3.1.1.1-04990-g3a7d1f4 (Nigel's 2.6.34 TuxOnIce tree).


I am testing 2.6.35.4 with TuxOnIce 3.2-rc1 on my ThinkPad T23.

After I few hibernation cycles I now got a backtrace on resume. I tried twice
before discarding the image.

I don't know yet, whether it happens regularily. I am attaching a screenshot of
the backtrace.
