Bug#496917: Soft Lockups
Hi Ben,
do you recommend using linux-image-2.6.26-2-amd64-2.6.26-21
for the host OS or for the guest?
I'm asking because with
host:
linux-image-2.6.26-2-amd64 version 2.6.26-21
kvm version 72+dfsg-5~lenny4
guest:
linux-image-2.6.26-2-686 version 2.6.26-19lenny2
the soft lockups still occur:
