Subject: Total loss with 2.4.0 (release)
Hi all,
I managed to kill my dear files and if anyone can help I'd be very
thankful. The events leading to this were something like:
Happy system with 2.4.0-test9 -> update to 2.4.0 (release) -> works
nicely; no complaints of any kind (no crc errors or dma-disabling) ->
reboot -> play Diablo II for some time (win98) -> restart linux ->
VFS: cannot mount root.
I have two ext2 partitions plus root and one of them is on another disk
(same ide lead, however) and it survived with no errors.
When I ran e2fsck (1.18) on root partition, in addition to having to
run it many times before succeeding (segfaulted sometimes), nothing was
left in the partition except lost+found with lots of
files. Valid superblock wasn't found at 0, but at 8193.
I really don't get what would have caused this or how to cure it. I
still
have my /home in need of repairing, but I won't be running fsck on it
with
this good expectancy-of-recovery (I actually tried once with a backup on
another disk and it resulted two VERY old directoried, everything else
was
lost...and found(?)).
I also updated my machine from VIA MVP3 based K6II to VIA KT133 (with
868B
southbridge - ATA100, that is) based Duron, but linux (2.4.0-test9)
worked
fine with both configurations. I think this might be some sort of DMA
problem.
I read from kernel notes that ac1 fixes root umount handling. Might that
be connected with the symptoms I had? If anyone has any suggestions,
please post them. I would, at least, like to know how could I verify if
the filesystem is really messed (for example, overwritten with something
at the bus at the time) or if it's just some minor issue that confuses
fsck totally.
