Subject: host panic on kernel 2.6.34
Hi all
I build latest kvm 37dec075a7854f0f550540bf3b9bbeef37c11e2a, based on kernel 2.6.34, after kvm and kvm_intel module loaded, then /etc/init.d/kvm start, a few minutes later, the system will panic.
kernel: 2.6.34
kvm: 37dec075a7854f0f550540bf3b9bbeef37c11e2a
qemu-kvm: 69dd59a66aaf56d1e8e4c96d0a0923c9cf8f79a0
