I've similar problem. Looks like --rebuild-tree finally fixed everything, but
there is a bug in reiserfsck because it doesn't see any errors while mount
unable to work.
I've a copy of this partition in file (3GB) on my harddrive in broken state
(i.e. before running any reiserfsck). I can't upload it, of course, :) but
if you wish to analyse it I can run anything you say on this file and send
you results. I'll keep this file while I'm waiting for your answers - about
a week.
(I'm not really subscribed to list, so please CC: me, but I'll monitor this
thread using web gate www.nabble.com anyway.)
I've no idea how filesystem become damaged. Only suspicious thing was dead
CMOS battery (this comp is old Celeron 333), but I don't really think dead
CMOS battery can affect this... So, linux was booted 2-3 times after BIOS
warning 'Press F1 to continue' and on next boot Grub refuse to boot with
'Error 17'. There no bad blocks on this partition.
I've moved harddrive to another comp and checked reiserfs, results is below.
Here is configuration of these computers (both has Gentoo Hardened
installed).

sys-fs/reiserfsprogs-3.6.19

If the partition table has not been changed, and the partition is

--rebuild-sb.

2.2, choose this one)
