extract files without mounting a partition?

extract files without mounting a partition?

[R Deepak]

Greets!

Can I ask support questions here? If not, sorry.. :(

I have a RAID0 config with 2 80GB SATA disks. I screwed up during an install 
and the super block got overwritten. 

When I ran reiserfsck on /dev/md0, it asked me to use --rebuild-sb Which I 
did. It reported quite a few errors and moved lots of files to lost+found.

Now the problem is that I am not able to mount this partition. I've tried 
with different kernels, gentoo 2005.0 live CD (amd64), knoppix (32bit), and 
an old gentoo 2004.1 (x86) live CD. 

As soon as I try to mount it, I get something like the following

ReiserFS: md0: found reiserfs format "3.6" with standard journal 
<kernel panic>
---------

Whole system freezes.

reiserfsck (latest reiserfsprogs) reports no errors with the device. I'm 
just not able to mount it.

What should I do? I atleast need to pull important files out..

Regards
Deepak

There should be more than that. Can you please show all kernel logs
related to the problem.

've attached the dmesg output and the output of "debugreiserfs
/dev/md0". Should I send you something else?

One  correction though.. the system didn't freeze. There was just an oops.

Please help..
