i believe the diff below should work out of the box. it pulls in
all mikeb's fixes.

With following Mike's suggestions it worked.
could you please change this line

this diff implements the disk cache ioctl handling in mpii so sd(4)
can drive the change rather than have mpii(4) whack everything.
modelled on the same functionality in mpi(4) and mikeb's code...
could someone test this please?

configured in RAID 1.
I had a kernel crash while booting amd64-stable kernel.
