I've updated kernel to RHEL6 042stab055.10.
And system is rebooting after saying "iTCO_wdt: Unexpected close, not stopping watchdog!" in /var/log/messages.

I've never configured IPMI watchdog timer.
so I wonder that message is appeared.

Unfortunately, the server which was rebooted with this message is not configured to take console messages and crash dump.
So I cannot explain details of this problem. sorry.
If someone can know about this, please tell me that.

I found a bug of stab055.10 which is related with this topic (see also: Bug2286).
This bug causes HN rebooting.

I found also a workaround. so if anyone has this problem, you should do the workaround (I wrote this workaround in bugzilla).
