reiserfsck --rebuild-tree fails

reiserfsck --rebuild-tree fails

[yurick]

        Hi!                                                          
   I have a 3.5 reiser partition, which I tried to fix by
reiserfsck ( --check, --fix-fixable, --rebuild-tree). I used
latest stable (3.x.1b) and also latest "pre" (3.x.1c-pre7) versions.
   They are fails to complete, so I can't mount my broken partitions
now :(.
	Output (last part) from reiserfsck 3.x.1c-pre7 is placed below.
Output from 3.x.1b is similar. Sorry for messed formatting - I grabbed
it by hand.

p.s. This box is running under 2.4.19pre9aa2 kernel, but I tried
2.2.19 kernel too - without success.

This one is very clear sign of broken memory or broken data exchange between
HDD and the box itself.
Try changing IDE cable/replacing memory/putting the HDD into other box.

    Thank you, I've tried other box and it helps. I am believe in reiserfs
again! :)
    Wouldn't be better to add advice about possible broken hardware to
reiserfsck when it prints such message?

Yes, this is nice idea. Thanks.
