Yesterday evening I have found the service responsible for the reboot

Anyone knows how to debug this?
Did you get anywhere with this?
Pretty nasty. Is there a bug open?
We're getting a timeout on an NFS mount during the powerdown
(single-node hosted, after global maintenance enabled and engine
powered off), and that makes the machine reboot and try to come back
up again instead of powering off.
So two issues:
- What is the mount that is hanging (probably an oVirt issue)?
Don´t know what that problem is. I have a local nfs mount but don´t
experience that problem
- Why does the system reboot instead of powering down as instructed (?)?
the reboot is caused by wdmd. Docs says that if the watchdogs aren´t
responding that a reset will follow. So our init 0 is overruled because
of the hanging watchdog. Why it is hanging I don´t know. Could be my
chipset, could be the version of wdmd-kernel. Only thing is I know it
didn´t happen always in the past but that is as much as I remember, sorry.
