reiserfs is broken on 64-bit machines. You'll need this fix:
From: Oleg Drokin <green@namesys.com>
>From the time of reiserfs_file_write inclusion all 64bit arches were not
able to work with reiserfs for pretty stupid reason (incorrect "unsigned
long" definition of blocknumber type).
Following patch fixes the problem.
