I have problems using the "20040119-fixed" partition
with 2.6.1 (after writing many MB of data, almost
always I obtain a file corrupted so that Oracle
doesn't start). With 2.6.0 and 20031223 snapshot I
have no problems using the "20031223" partition.

But in both tests I saw that fsck.reiser4 gave me
from 5 to 35 and more corruptions errors, all of type

Error: Node (210326), item (7): StatData of the file
[10001:1616662635f5445:10002] has the wrong bytes
(3625472), Should be
(3629056). Plugin (stat40).

So I was thinking (perhaps strangely ...) that this
kind of corruption was more dangerous with 2.6.1 +
20040119-fixed (I'm speaking about Oracle logfile
corrupted after 5 million rows written) than with
2.6.0 + 20030123 (which never gave me an Oracle file
corrupted, also after 10 million rows written).

I made the same test on 2 different disks so I'm
almost sure this is not an hardware problem.

Best regards

Paolo
