Nice. Andrew, any chane you could test this patch on the affected
Xen hypervisors? Was it as easy to reproduce this on a RHEL5 (U1?)
hypervisor or is it really only on Linode and Amazon EC2?

Originally, I was able to reproduce the issue easily with a RHEL5
host. Now, with this patch it's fixed.

OK, so Tested-by: Andrew Jones..
and from my perspective it looks good - so Acked-by: Konrad Rzeszutek Wilk [off-list ref]

Andrea, any chance you can respin this patch and send it to Linus for 3.5 please?
