Hey,

2.6.32.16 fails to boot on my KVM domains using qemu-kvm 0.11.1.

Bisecting between 2.6.32.14 which worked and .16 turned up this commit
as the first culprit[0].

The host is still running 2.6.32.14 and has 8 cores on 2 CPUs.  The
single-cpu KVM domain hangs just after printing 'Write protecting the
kernel read-only data: 9492k'[1].   On a successful boot this line would
usually be followed by 'INIT: version 2.86 booting'.

A 2.6.32.16 with this patch reverted boots fine.

If there's any info you need please just ask.

Cheers,
Peter
