Hello
I have used my 2.6.32.20 config and compiled now a 2.6.32.22 from kernel.org.
2.6.32.22 has the important security fix (local user can be root with a
exploit).
When booting up the domU with the new kernel, it hangs here:

dom0 is XEN 3.4.3 selfcompiled on Debian Lenny amd64.
Hardware is Supermicro Board with XEON E5506 CPU.

Did it used to work before? With 2.6.32.20 ? Was that kernel from
kernel.org too? Did you try to bisect the kernels to see which git commit
from 2.6.32.20 through 2.6.32.22 caused the failure?

2.6.32.21 boots fine on Xen. 2.6.32.22 does not due to NULL rip, so it
is probably related to the security fix that was done. Will bisect
later.

Aiee - that's not good. I see the problem, but I'm not sure why I
didn't see it in testing. Patch shortly.

No, its a little more subtle than I first thought (which is just as

guessing its a race where the timer interrupt is being enabled too early
before its irq state has been set up properly, but I need to look at it
a bit more closely.
