I had to hard shutdown a fc6 machine due to vmware and nvidia doing
ridiculous things to my screen resolution and locking up. ugh.
Anyway, upon reboot it recovers the journal and mounts / rw fine.
Then rc.sysinit tries to delete various things from /tmp (.ICE-unix,
.font stuff, etc), kernel shows a BUG, and boot stops. Booting from a
fc7 live cd and trying to mount /dev/sda2 rw and delete /tmp/* also
causes a BUG. This dump is from fc7:
eth0: no IPv6 routers present
kjournald starting. Commit interval 5 seconds
EXT3 FS on sda2, internal journal
EXT3-fs: mounted filesystem with ordered data mode.
SELinux: initialized (dev sda2, type ext3), uses xattr
inode_doinit_with_dentry: getxattr returned 5 for dev=sda2 ino=13271075
EXT3-fs warning (device sda2): ext3_unlink: Deleting nonexistent file
(13271075), 0
list_add corruption. next->prev should be prev (e8a1412c), but was
e8b4ba78. (next=e8b4ba78).

Obviously, ext3 was not consistent after replaying the journal which
should never happen. Do you have somewhere available the original
filesystem image or at least messages from fsck when fixing the
filesystem?

This is a corruption of superblocks orphan inode list. Probably it is
a result of previous fs corruption...

Unfortunately, no. I did not think of logging the fsck output :( I
recall hitting 'y' to fix about 30 things, with the last fixes being
something like superblocks not matching each other which I hadn't seen
before. This machine had also been hard powered off at least 5 times
before in the last few months (due to nvidia lockups).

The corrupted orphan inode list bug I fixed,
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2988a7740dc0dd9a0cb56576e8fe1d777dff0db3
is in that fc7 kernel, so that's probably not it (though your fc6 kernel
probably didn't have that fix) (it's related to link & unlink racing)
Perhaps this could be related to Vasily's issue w/ bad_inodes not
getting removed from the list ?
[RFC PATCH ext3/ext4] orphan list corruption due bad inode
http://lkml.org/lkml/2007/6/4/7
I haven't looked at all the ways we could get bad inodes on the orphan
inode list, and not properly removed...
