Hello,

The host is not running an NFS server actively, the option may be 
compiled in but it is not 'acting' as an NFS server/has shares exported. I
need stability for this specific host, I cannot run netconsole due to
restrictions etc/will switch to ext4 since, if it recurs again, all I/O to 
the disk stops and I will not be able to assist in reporting the 
bug/giving the full output.  If I could reproduce the bug in another 
environment, I would be able to troubleshoot the problem more..  This bug 
is very similar to the one I reported in the past (that host was an active 
NFS server):
