[CentOS-virt] init 6 works inconsistently in XEN

I am using Centos 5.2 as both my XEN host and guests.  Both the XEN
host and each XEN guest are up-to-date with the latest CentOS 5.2

I've noticed over time that sometimes using init 6 (or init 0) in the
guest works flawlessly and other times the guest will reach
"Restarting System"/"System Halted" and hang.  When this hang occurs
the only way to finish the shutdown/reboot is to destroy the virtual
machine and also one of the CPUs on the XEN host is maxed out at 100%

Trying to diagnose this hang, I have found that restarting the xend
and xendomains daemons restores the ability to init 6/init 0 the
guests. I have not as yet narrowed the problem further.

I was wondering if anyone else has seen this behavior and if so if
there is a known fix, if not, how to properly report this issue so it
can eventually be addressed?
