I can't do any testing at the moment but I have also seen this problem with a Highpoint 2240 RAID card and a 5TB JFS filesystem on later 2.6 kernels. nfsd deadlocks after a short period of time and can not be killed. The only way out is to hard reset the machine or send the reboot immediately command through sysreq. > > Are there any errors in the syslog?
