Same problem as Message #30...
Which message #30? Where that message is?
My kernel is Linux 2.6.32-4-amd64 (see Message #35)
Which message #35?
I'm using http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569990 where
you can find Message #30 and Message #35.
Here you can find all the screenshots of the bug. I haven't find another
way to log the crash...
with kvm it's quite easy to do actually. After all, it's trivial
to set up a serial console, with `-serial file:output' option for
kvm (and add console=ttyS0 to the guest kernel command line).
Provided it's guest kernel which crashes. If it's host kernel,
the thing is entirely different.
/mjt
Thank you for the help... Yes, it's the guest kernel which crashes. And
I get the output file.

Here's the result of the output.
