EXT3-fs error on 2.6.0-test7-bk4 (and -test9)



ext3 is having big problems on my x86-64 system. An ext3 partition has
just gone crazy, with the following messages in dmesg:

EXT3-fs error (device hda3): ext3_readdir: bad entry in directory #4603905: rec_len % 4 != 0 - offset=0, inode=2507704792, rec_len=42,
name_len=0
Aborting journal on device hda3.
ext3_abort called.
EXT3-fs abort (device hda3): ext3_journal_start: Detected aborted
journal
Remounting filesystem read-only
EXT3-fs error (device hda3) in start_transaction: Journal has aborted
EXT3-fs error (device hda3) in start_transaction: Journal has aborted
[...]

I hit a similar problem yesterday, but lost some details so I couldn't
make a proper bug report. However, it did mean that the partition got
fully fscked, so I think these errors are ext3 getting confused all by
itself, rather than it complaining about an already-corrupt filesystem.
There's no sign of any hardware problems with the disk or controller in
the logs.

No extra ext3 parameters were set when mounting this partition
originally.

Going back through the logs, there are also these worrying messages
(from the previous crash):

attempt to access beyond end of device
hda3: rw=0, want=24855217912, limit=143235540
attempt to access beyond end of device
hda3: rw=0, want=7590624504, limit=143235540
attempt to access beyond end of device
hda3: rw=0, want=17158939432, limit=143235540
attempt to access beyond end of device
hda3: rw=0, want=32230066456, limit=143235540


Is there any other information I can supply to help track down what's
going wrong?
