The raid 5 volume on the MegaRAID i4 is about 480GB and is comprised of
four different disks (one 160MB, two 200MB and on 250GB).

After applying you patch to -current (today), while doing newfs on the
raid volume we fail.

(lots of numbers)...
61851520, 62183204, 62513088, 6284372,newfs: wtfs: write error on block
63174688: Input/output error
sd0: WARNING: cache ssyncronization failed

I did the typical ``fdisk -i sd0'' and ``disklabel -E''to create a
single "a" partition on the volume.

I'm going to back the patch out and see if it makes a difference..

If you have something specific that you want me to test, let me know.
