If you set the stripe_cache_size less than or equal to the chunk size of
the SW RAID5 array, the processes will hang in D-state indefinitely until
you change the stripe_cache_size to > chunk_size.
Tested with 2.6.22-rc6 and a 128 KiB RAID5 Chunk Size, when I set it to
256 KiB, no problems. 128 KiB and below cause issues.

There is some kind of bug, also tried with 256 KiB, it ran 2 tests
(bonnie++) OK but then on the third, BANG, bonnie++ is now in D-state,
pretty nasty bug there.
