The same thing happened to me today (kernel 2.0.33). It seems to be a
smbfs bug.
I had a smb filesystem mounted from a Win95 box and was copying some files
when (of course) win95 crashed. The cp command was hung with ps showing
it waiting in tcp_recvmsg for a packet which would never come. There was
also a 'ls' command in disk wait on the smb filesystem.
Upon giving the cp process a kill -9, I got:

It crashed my X server too, as if it had run out of memory, but there was
plenty of RAM available. The weird part is that the 'ls' was left in the
process table with no pages mapped (after I kill -9 it):
