Can you send your fixes to the list?  At least then everyone else doesn't
need to fix the same bugs.  It would be even better if Heinz made a new
bugfix release, but I watch the list for fixes anyways...

No journalling filesystem will work properly with RAID 5 - not reiserfs
and not ext3.  You need to stick with a non-journalling filesystem, or
use RAID1.  It may be that this is supposed to be fixed in 2.4, but I'm
not 100% sure...
