Server hangs after typing reboot command

Question

I have a Debian Wheezy installation with Xen in kernel. All is fine but ... when I type a reboot command or shutdown -r now, my server is stuck and I see only that info on screen:

INFO: task reboot:15065 blocked for more than 120 seconds

I tried to change the kernel from wheezy to a kernel from backports - 3.10-0.bpo.2-amd64, but it doesn't help.

Do you have some idea why and what is the problem?

Thank you for help.

Best,

Rafal

You'd probably be better off asking on the Debian Forums. Sounds like some kind of bug. — Chris S, Oct 02 '13 at 13:55
What hardware do you have? I had a machine once that hung with messages similar to that...it was the RAID controller. One firmware update later and it's worked fine since. — Nathan C, Oct 02 '13 at 14:26
I have Dell PowerEdge r720xd wirh Raid controler. Hmm maybe i have to upgrade firmware raid. I've checked logs and only that i have in dmesg. — Rafał Kamiński, Oct 02 '13 at 15:37
Your server is a Dom0? Did all DomUs shut down before that reboot? — Nils, Oct 10 '13 at 19:51

The log you provided indicates an I/O problem.

You can start looking at and testing it with vendor provided tools. It can be that this is not a hardware problem, but a Xen problem with insufficient I/O performance.
