Just had a third oops in 2 days -- the first two were during a download
to a vfat partition, and the second one was during a download to an ext2
partition, right after a cp to a vfat partition followed by a rm and a
df, which was where it oopsed.

I was only able to get the second and third oops totally, as they didn't
show up in any logs and didn't allow any new programs to be started;
however existing programs seemed to continue to function properly until
quit.
