Error in reiserfsck 3.6.19

[Adam McLellan <alphanos@gmail.com>]

Unless I'm doing something wrong, there is an error in reiserfsck
3.6.19.  It's actually kind of a humourous error; it doesn't divide
correctly :-).  I've been going through a somewhat lengthly process to
diagnose the problem with my reiserfs filesystem, and finally got to
the point where I'm ready to rebuild the superblock.  Here's the
output:

So far as I know, 1024 * 16 = 16384.  I'm currently running on a
Knoppix 3.9 CD, using the included reiserfsprogs package.  It uses the
2.6.11 linux kernel.  My system doesn't have any stability issues that
should cause it to divide incorrectly :-).  Since this appears to be
an interface error rather than an operation error, I don't think my
kernel modules are relevant, but a log of sorts listing all of the
steps I've taken to diagnose my problems since they started can be
found at http://forums.gentoo.org/viewtopic-t-371570.html.  It
contains a lot of information about my current setup, but much of the
early text refers to attempts to check for hardware problems and to
fix a software raid problem.

If/when I can get past this error message, I hope I am correct in
assuming the the program shouldn't have any trouble actually
performing the superblock rebuild with a block size of 16384?  I've
been running this filesystem for two years with that block size, and
am not ready to give up the data on it just yet :-).

Thanks for any help with this problem, and also for the wonderul file
system :-).
