Robert,
That output below is part of the results from
reiserfsck /dev/hde5
(obviously /dev/hde5 is the partition that I checked). I'm using reiserfsprogs version 3.x.0i. You can run reiserfsck without any arguments and it can't do any harm to your partition - it's read-only.
I tried "reiserfsck -x /dev/hde5" but that didn't fix anything. (the -x switch is supposed to "fix fixable without having to use --rebuild-tree). But
reiserfsck --rebuild-tree /dev/hde5
fixed the bitmap problem in this case, and it didn't cause any new problems. Nevertheless, I'm using reiserfs on all my machines, so I would be glad to help debug the problems asap - I'm worried about losing a whole partition here and there eventually. I'd go back to kernel 2.2.18, which is supposedly very stable, but I can't. It doesn't work for me on reiserfs partitions created with 2.4.x.
I don't know where to start with debugging, either, but I'm willing to take instructions.
