REISER4 corruptions errors

In my last message "REISER4 strange partition size"
I wrote:

"... making intensive writing test on this
reiser4 partition (for example: writing 1 million rows
on an Oracle table in archivelog mode) on each test I
obtain a corrupted redolog file [sometimes is
recoverable, sometimes I've to rebuild the entire
DB)."

And Nikita answered:

"It is not clear how to diagnose this. What oracle
are you using? Is it available freely?"

Really I think this test is not so easy to prepare
(you have to download Oracle, install it and bla bla
...) but I think my last test is more "human".

I recomplied Kernel 2.6.0 with
CONFIG_REISER4_BADBLOCKS=y

I'm using 2.6.0 + 20031223 snapshot because 
2.6.1 + 20040119_fixed always gives me some file
corrupted and I was spending too much time re-creating
Oracle DB.

Reiser4 partition is mounted with tmgr.atom_max_age=20
option.

I noticed that if you copy a large amount of data (at
least 500 Mb) from a partition to a Reiser4 partition,
umounting Reiser4 part and using fsck.reiser4
you always obtain from 5 to 40 (and more) fixable
corruptions detected.

It seems that with 2.6.0 + 20031223 snapshot these
corruptions are not so "dangerous" to corrupt files
(I mean, also with these corruptions I'm able to work
with Oracle). Unfortunately I cannot say the same
with 2.6.1 and latest snapshot.

Any idea ?

All the best

Paolo
