2.1.106 SMP ntfs Oops

What I was doing:
I had never tried reading the ntfs disk before, so I mounted
it with no options first. I saw that mount thought it was
r/w, so I unmounted it and mounted again with -oro. I used
ls a couple of times, then tried find to find the file I was
looking for, and it gave me a few matches, then find crashed
with a segfault, and I found the following oops in the log.
The machine is still up, but it won't let me unmount the ntfs
drive (no big deal since it's readonly). ntfs is a module.

Hardware:
4 200MHz PPro processors
256MB RAM
Matrox Millenium PCI 4MB RAM
2 AIC 7880 SCSI controllers on board, BIOS v.1.26B3S2
3-button ps/2 mouse
Intel 82557-based PCI ethernet
IDE CDROM on primary master
1 9GB Seagate drive with NT on the first SCSI controller
1 1GB old IBM AS400 drive with Linux on second SCSI controller
