Linux-2.4.4 has serious reiserfs bugs fixed.

What kernel messages were ?

Sorry, but it looks for me like a lvm problem.  Can you test you LV by
coping some random data (~ 64 MB) to a file in reliable location and
to LV, and compare them (or md5 hashes) after reboot ?

 PB> i had to reboot because something oopsed:

Reiserfs error handling not an ideal one.  Kernel oops below is a
normal :( reaction on damaged data coming from disk.

Same reason (damaged data), I think, prevented reiserfs volume from
mounting.
