Hi,

my 8-core amd64 machine crashes when I'm trying to run my module. The  
problem is that I can't debug it, since core dump is broken.

I can obtain correct coredumps when I'm running everything inside  
QEMU, but not when I'm running on a real machine. Also, panic doesn't  
occur inside QEMU :(

Any hints?

Cheers,
Nikola
