It was no offense intended from my side. I'm totaly aware what we got
for free from you and your team. I was only wondering way my short
poking around revealed two kernel panics without any esoteric
configuration/load involved. So i was wondering if i try to upgrade
too early or if no one is using the RHEL6 OpenVZ kernels seriously
until now. The first panic is already reported the second will follow
as soon as my test server has finished fschk.

Regards

Andreas
