2.0.32 : general protection: 0000

Hello all,
I am running linux 2.0.23, 48M RAM, AHA1542 SCSI Controler, 1
SCSI Drive, 2 IDE Drives, IDE CD-ROM, 64M Swap. At the time of
this problem I was in X running netscape with 4 browsers open, 11
xterms, playing a MP3, running mySQL, and was generating about 6M of
html documents from the database with a perl script. I also had a ppp
connection to my ISP, with ip_masquerading. I clicked on netscape,
and all of a sudden I was looking at the login prompt on the console.
I check my log files and found that the message below was logged
by klogd:

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):
