Hi,
I managed to have a kernel panic with the following kernel:
http://mirrors.ch3rry.be/openvz/kernel/packages/sys-kernel/l inux-openvz-2.6.32.61.2.tbz2
I stopped the /etc/init.d/vz process, and then try to start a
container, and then the kernel crashes:
============================================================ ====

I will try to have the full console to see if I can grab more kernel messages.

Here is the console capture attached.
It complains about "bad_area_nosemaphore":
(sorry but gocr does not output the right message, see the attached pic)
