Don´t know what that problem is. I have a local nfs mount but don´t 
experience that problem

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.
