vmwrite error after upgrade to pve-kernel-2.6.32-22-pve

Hi all,

I've just updated my proxmox servers with the latest updates. This included the update of the kernel from pve-kernel-2.6.32-20-pve to pve-kernel-2.6.32-22-pve.
At 2 of the 4 nodes this kernel message is logged when starting an vm on the node (or migrating to).

When booting with the previous kernel, pve-kernel-2.6.32-20-pve, no errors occur.
Although, even the error occurs, the vm's run fine.

The 4 nodes are not identical hardware.
The nodes with the errors have (older) Xeon 5130 cpu's. The nodes without has (less older) Xeon E5420 cpu's.

I found this: http://git.kernel.org/cgit/linux/ker...049a56e61659f0
Which seems to be the exact issue. Will this patch be included in future pve kernel versions?

Regards,
Hugo
