Subjectsysv filesystem lockups
I've experienced a number of system lockups after accessing sysv
filesystems mounted on loopbacked files. These lockups don't always
happen at the same point in the filesystem, so I don't think they're
due to corrupt filesystems. [Sometimes I can mount the file system,
copy the entire thing, then unmount safely. Other times they happen
rather quickly.]

These lockups happen much more rapidly when the underlying file is on
a umsdos file system than when on a ext2 file system.

This is with a 1.3.88 kernel (as are the bugs I reported earlier today
-- don't know if I mentioned that bit then).

This lockup prevents new processes from getting anywhere.

[I was going to take some register snapshots with alt-scrollock, but
somehow it wasn't working for me. I think it's because I tried
left-alt scrollock rather right-alt scrollock, but the lockup is
rather distressing, and I'm not eager to repeat it.]

Is there anything in particular I should look for?
