This has been reported twice in the last couple of days from the cvs
kernel, one was after a clean unmount! Most of the log looks good,
but something in there is invalid, xfs_logprint gets confused as well
and core dumps or trips an assert.
Long term it would be nice if we could make log writes stripe aligned
which would probably also fix this (currently they are any old 512 byte
multiple long on any 512 byte boundary). However, it should work without
this. Try a default (small) log, zero it with xfs_repair, then mount,
do something, unmount. Repeat until it does not mount, look at the log
with xfs_logprint - there is a binary dump option which should not
fail. If there are zeros in the middle of the log then we have a problem
in the raid code.
