Neither oops caused the machine to reboot.  The /boot/System.map 
file was for 2.4.14-pre4, and these ksymoops were taken before 
I rebooted.  I pasted the oops from /var/log/kern.log and passed 
them to ksymoops without any arguments.

vmstat, iostat, and ps all would not return a prompt.  I could
exit shells, and IRC clients.  init 6 hung sending kill to processes
started by init.  <sysrq Sync Umount> worked.  Hit the reset button.
Thanks to the kernel hackers and reiserfs folks it came up clean.

This oops came during the mtest01 run.

This oops came after the tests completed and I hit 'q' to quit mp3blaster:

I see pre5 is out there, and it's still early.  :)
