Hi,
I'm have a little problem with my reiser4 partition...
I can't mount it anymore and I'm unable to repair it.
I have a AMD64 platform with 64-bit Gentoo installed.
Here's the short story:
1. I was using kernel 2.6.16 with reiser4-2.6.16-4 patch
and I installed new 2.6.17 kernel with reiser4-2.6.17-3
patch. (The kernel source is Gentoo-sources since I'm using
Gentoo :)
2. After rebooting with .17 kernel I ran fsck.reiser4
on my reiser4 partion (an error was reported in the
system log earlier, saying something about keys are
inconsistent..).
3. I rebooted (again) after having to do fsck.reiser4
--build-fs and then my system refused to boot. The
screen filled with errors telling me about inconsistent
keys etc.
4. I tried to run fsck.reiser4 through two different
reiser4-capable LiveCDs but with no luck. The fsck.reiser4
always segfaults after 2% of the whole process. First
livecd had some .17 kernel and the other .14 kernel. Both
have reiser4tools-1.0.5.
Here's the output:

# fsck.reiser4 -y /dev/hda3

It does the same with all option (--fix etc).
Here's the output when I try to mount the partition:
--- Cut ---

The system log says nothing. I'm a bit lost what to do.
I had some important files on that partition (and yes,
I should have done a backup). Is there a way to fix the
partition?
