Subject: Re: paravirt clock stil causing hangs in kvm-65

Hi Glauber, sorry for late reply.
well, I'm no longer able to reproduce the problem in the same way (with 
backtraces etc) as before, but anyways enabling paravirt_clock with or 
without Your patches on SMP guest still causes troubles:
on my phenom machine, the kernel hangs after printing
"PCI-GART - No AMD northbridge found."

on intel machine normal system boot seems to be terribly slow taking tens 
of seconds between steps and later hangs, using init=/bin/sh seems to work 
though.

I'm wondering how can I get the backtraces I was getting before, I have 
soft CPU lockup debugging enabled, what else could help?

cheers

n.
