Are you saying I can use the standard 2.6.38 build as a Xen Dom0 kernel?

I really wanted stable and tried the latest 2.6.32.XX from two weeks ago but on every machine I've tried it, I got a kernel panic in xen_set_pte. I wasn't sure what the root cause was (I upgraded from 3.X to 4.X Xen at the same time) so I tried 2.6.38-rc7 to see if it was Xen or the kernel and no longer got the panic, so continued with that kernel version. I was under the impression that 2.6.38 would be a stable version, but not it appears not. Is there a version later than 2.6.32 that I could use a stable? thanks, Anthony.
