shutdown kills raid daemon before drives get unmounted

User-Agent: Mozilla/4.72 [en] (X11; U; Linux 2.2.13 i686)
Description of problem:
During shutdown it gets to "Sending all processes the KILL signal..."
Then there are some messages from the raid system:
raid5d(122) flushing signals.
md: recovery thread got woken up ...
md: recovery thread finished ....
mdrecoveryd(8) flushing signals.
md_do_sync() got signal ....exiting
raid5: resync aborted!
When it gets down to Unmounting file systems it hangs. I presume this is
because the raid daemon is dead by then. The filesystem on the RAID is
reiserfs, so it's not that big a deal to hit reset and let the box come
back up. But it's annoying that it hangs and it does take a minute for the
ext2 file systems (/ and /boot) to clean themselves up.
Steps to Reproduce:
I don't have any other systems with RAID drives so I can't say that I've
reproduced it. But it does do it
Expected Results: I would have expected the box to shutdown cleanly.
I've installed all the updates after doing a clean install on this box.
I had RH6.2 and an ext2 filesystem on a RAID in this system before without

output of mount
Hangs usually only happen when unmounting NFS file systems - just sit and wait
for things to happen.
Sorry, that's about the only explanation I can think of besides slow hardware,
which you probably would have already factored in.
