CPU Softlock is back again, how to roll back kernel ?

[nsc]

Hi,

In November / December 2010 i had some random "CUP softLock Error" in an huge KVM (4 vCPU / 12Go RAM) : VM just hang forever, i have to stop / start...

Finally in December i moved to 2.6.32-4 (i was using 2.6.32-3) from 26 November (not sure) and all my problems were gone ... My VM was fine 45 days withtout any problem.

This week-end i upgraded my proxmox to latest kernel (15 December) and the CPU SoftLock are back again 2 times since Saturday...

Is it possible to roll back kernel to confirm ?

Thanks

Nsc

you can try one kernel from here (just wget and dpkg -i)
