This is the *strangest* mauling I've taken in a while..
After firing 45-7 up and running a few tests, I decided to run lmbench. Since
it wasn't resident in 45-7's cage (chicken!), I had to let it out.. mistake.
Mounted /dev/sdb3 on /mnt, and promptly remember that I moved lmbench out of
this partition (/usr).
Mounted /dev/sdc1 on /mnt2 (/usr/local/src). As soon as it mounts, 2 ext2fs
messages go past.. too fast to read.. become *very* observant.
Do ls /mnt2, and see my /usr tree. Hmm?! ls /mnt, and see my /usr tree.
Do df, and confirm that two different drives are in fact mounted.
Reconfirm that both /mnt and /mnt2 show the identical content.
AOOOOOOOOOOOOGAH! DIVE! DIVE!
umount.. groan..

Boot 2.0.30+++ and let Ted try to fix the damage (lots of directories).
Afterward, I had to find a few directories and put them back where they
belong, but only lost one file (wow!). My /usr/src/patch dir ended up in
/usr/src/v2.0/linux/drivers/pci/.depend.. but was intact. File .depend got
morphed into a directory.. wonder where the .depend data blocks went.
I'm going to make another pen for it, and see if I can reproduce this :-/
-Mike
P.S.
After piecing the fs back together, I ran a bunch of make -j etc. all ok.
But, fired up X in the middle of 2 make -j's and got the strange /proc
related oops which I reported earlier.
