Ok, I tried the NFS mount command again but without dnetc running. (BTW, I'm running rpm -Uhv to update some packages from another linux machine; I download the updates on it and all other machines load the updates from it.)
This time I got a stack dump to run through ksymoops:

I was able to copy-paste the message on the screen into a file so I didn't have to type it in manually onto another computer. I rebooted the machine after this just in case something somewhere might've been unhappy about this. While it was shutting down, the NFS mount point refused to umount, saying the device was busy. The only thing that could've been using that mount point was the rpm command that I ran. I cd'd back to /root before doing the shutdown -r now command.
This machine is a dual P2/300 w/320MB memory and no bigmem support compiled in. NFS is compiled into the kernel (not a module) as is the eepro100 network driver.
