Try giving the VM a second virtual CPU, if you have only one CPU and it
gets hung sufficiently hard, the debugging stuff won't have a chance to run.
Oh, and make sure you configure your kernel for SMP.
It has 4 cores and kernel is already configured for smp.
Sysrq is a pretty cool option, but other than reboot almost no other commands run including 'e', 'f', ;i;.
It seems I might have to resort to debugging by the process of elimination (removing code until it doesn't hang and so on.. ).
Any other ideas I would appreciate it.
