[CentOS-virt] Xen4CentOS kernel panic on dom0 reboot

[Karl Johnson]

Hello,

I've been using Xen4CentOS for the last 3 months. It's working fine and
dom0/domUs are stable but the server does a kernel panic when doing a
reboot and the server has to be hard reset manually. It has kernel panic on
the 3 last reboot.


Please stand by while rebooting the system...
INFO: task reboot:19800 blocked for more than 120 seconds
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message
Call trace
...

Picture of the call trace: http://i59.tinypic.com/169olt1.png

CentOS: 6.5
Kernel: 3.10.23-11.el6.centos.alt.x86_64
Xen: 4.2.3
Server: Supermicro 6017R-WRF

Any idea how to troubleshoot or fix this issue? We can't reboot the dom0
during the week because domUs (2) are in production and this server is in a
datacenter.

Kind regards,

Karl
