Hello,

Just installed clean Debian 6.0.2 amd64 and did a reboot via shutdown -r now . This is what I am getting:

can you retry without that vboxfoocrap.
Is it reproducible then?

thank you.

It seems like it just happens once.

I will try to repro it with vbox. Will make sure that I have a solid test-case scenario and then will test it without vbox.

Speaking
of testing modules. Is there any thing in Linux as Driver Verifier
which is used in Windows? It allows to check for pool corruptions, page
faults when called at high IRQLs, etc. I assume there are none for
Linux.

Is there any trick I can do to hunt this bug down?* Like compile
kernel in debug with special asserts? But in this case I will change the
code base basically ...

There are build-time options to enable such checking in the kernel. See
the options under "Kernel debugging" (CONFIG_DEBUG_KERNEL).
