[grsec] KVM soft lockup

[Bastien Durel]

Hello,

I recently decided to upgrade my KVM guest server.
It used to run a Debian with 2.6.32.24-grsec/i686 custom kernel.
My new server is an i7 with plenty of RAM, so I decided to switch to an
amd64 kernel.

With squeeze stock kernel (2.6.32-5-amd64), KVM runs fine.

I then compiled a 2.6.32.27-grsec custom kernel, but when I run KVM with
this kernel active, I get some 
BUG: soft lockup - CPU#x stuck for 61s! [kvm:xxxx] 

then the whole machine become unresponsive.

Is there any known incompatibilities ?

Thanks,
