It probably broke suspend at some point... leave it there. Processes can stay in D period, waiting for NFS server to come back. and yes, we want nfs threads frozen, too (and anything that talks to network). Speaking to nfs servers while we are suspending the machine is not nice, and if that continues after snapshot, we'll act as a very confused machine to the outside...
