Default Bug#644212: linux-image-2.6.32-5-amd64: kernel BUG at kernel/exit.c:1035: "invalid opcode: 0000"

Package: linux-2.6
Version: 2.6.32-35
Severity: normal

The stack trace can be seen below; if it matters, note that the machine
a) is running under KVM, b) has relatively high CPU & I/O load c) it's
the first time it has BUGed, although it has been running with 2.6.32
since April and with 2.6.32-35 since early August.

Thanks,
Faidon

Well this is pretty damn weird. This BUG message means that the
scheduler reselected a task to run after it exited (i.e. it was a
zombie).

I can't find any related bug reports or fixes. I'm afraid we are
unlikely to be able to progress this unless it is reproducible.

Ben.

Yeah, I figured it was weird... I don't think I'll be able to reproduce
this, it wasn't even triggered by user action (the process that crashed
it is a daemon) — and as I said, it's the first time it's being doing
this in quite a while.

If you have any ideas on how to reproduce it or get more info, I'm all
ears :-) The machine is, surprisingly, still up and running although
I'll have to reboot it (just to be safe) soon.

Thanks,
Faidon
