I've just installed 2.0.5, and it's running nicely... but without
msdosfs, and only after two system panics which both wiped out /usr
totally and forced me to reinstall.

msdosfs is pretty clearly the culprit in the panics: when I added a /dos
mount point for the DOS partition with which FreeBSD is sharing the disk
(in disklabel during the install -- I haven't played with adding it any
other way), the system ran fine *until* I read or wrote anything in /dos
-- shortly after which point it trashed /usr totally and then panicked.

It did give fair warning, though: when booting with the mount in place,
mount_msdosfs complains about a misaligned partition.

(System profile: Pentium 100 w/ 40MB, running a 1GB Conner disk through
an Adaptec 2940.  Other periphs, almost certainly irrelevant to this
problem, are a Paradise Viper Pro VLB (4MB VRAM), a SCSI CDROM, and an
HP Travant FD-type tape drive.)

It would be really nice to have access to the DOS partition from
FreeBSD... any advice will be much appreciated.

(If I can't get access to the DOS disk, can somebody give em a quick
rundown on using my QIC80 tape from FreeBSD so I can move some stuff
over that way?)

Thanks,

Richard
