Hi, I have a strange problem with a partition w/ reiserfs. After a power loss, the partition has been damaged in a way reiserfs doesn't seem to handle correctly. When mounting the partition, there is a segfault. The original system was a SuSE 8.0 (kernel 2.4.20) I did a 'reiserfsck --check ' , then a 'reiserfsck --fix-fixable' : no errors found/fixed. I then tried 'reiserfsck --rebuild-sb' and 'reiserfsck --rebuild-tree' : some errors fixed, still segfaulting. Finally, 'reiserfsck --clean-attributes' : no errors found, still segfaulting.
I then tried with a recent SuSE live CD (10.0 - kernel 2.6.13) : same error.
Finally, I used sysresccd (kernel 2.6.16.10) to save & restore the
partition with partimage, hoping that it would rebuild a clean partition.
-The save was ok.
-I then reformatted the partition with r/w check - ok.
-The restoration worked.
I then tried to mount the partition : still the same error. Damn!
Here the error :

I also googled a while, but I only found a post (was in 2005 I think), with
the same error, but to which nobody answered.
An idea someone?
