Ok, I continued to develop on the patch which tries to allocate per cpu
stats from worker thread context. Here is the patch.
Can the reporter please try out the patch and see if it helps. I am not
sure if deadlock was because of mutex issue or
happened with two servers (same hardware, same build group so there
is a chance of a bad hardware batch). Switching to an older kernel/kvm setup in
RHEL 6.2 has corrected the issue, which suggests a software issue to me.

I have seen this behavior on two machines (dual E5606 running Fedora 16) both
passed cpuburnin testing and memtest86 scans without error.
I have reproduced the crash and stack traces from a Fedora debugging kernel -
3.1.2-1 and with a vanilla 3.1.4 kernel.
