Thank you!

The problem is I use XEN kernel from CentOS and I really don't want to
mess up with manual compilation of every new kernel that comes out...

Do you know if RedHat incorporated this patch already?

If not, I'll keep up with AVT - it seems that works OK. Some paths fail
every now and then but are back online in just a couple of seconds, and
that is currently OK.
