I was running 2.1.31 and just had it eat my root disk. I was logged in
remotely so I did notice the problem until applications started
complaining they couldn't map libc.so.6. After rebooting on my old disk
fsck showed that file system was in really bad shape. I've seen no
corruption with my 2.0.29 kernel. The system was running the normal set
of remote daemons, but shouldn't have been processing anyting. I had
recently run a Dec Unix 4.0 binary. The messages log shows a bunch of
lines like:

Apr 4 10:24:04 sw-linux-2 kernel: 7
Apr 4 10:24:05 sw-linux-2 kernel: EXT2-fs warning (device 08:02):
ext2_free_blocks: bit already cleared for block 21207
Apr 4 10:24:12 sw-linux-2 kernel: 08:02: rw=0, want=1312820500,
limit=1965755
Apr 4 10:24:12 sw-linux-2 kernel: attempt to access beyond end of
device

This is an Alpha with an Adaptec 29040UW and a Seagate fast wide
disk. Just thought I could add another data point.
