Subject: Re: cpu stall and hyperthread

I installed the exact same system on a machine. This time the CPU is 
Core 2 Quad Q9650.

With 3.2.18-rt29, this system is very stable. I haven't encountered a 
single CPU stall problem.

So it seems to me that the combination of PREEMPT_RT, i7 and KVM is not 
the right combination :( It always causes cpu stall.

Thanks,

Dong
