It seems that the same bug that initially stopped ataraid working
at all is there with rebuild:

kompak# atacontrol rebuild 0
ad4: FAILURE - oversized DMA transfer attempted 131072 > 65536
ad4: setting up DMA failed
kompak# atacontrol status 0
ar0: ATA RAID1 subdisks: ad4 ad8 status: REBUILDING 0% completed
kompak# atacontrol status 0
ar0: ATA RAID1 subdisks: ad4 ad8 status: REBUILDING 0% completed
kompak# atacontrol status 0
ar0: ATA RAID1 subdisks: ad4 ad8 status: REBUILDING 0% completed
kompak# atacontrol status 0
ar0: ATA RAID1 subdisks: ad4 ad8 status: REBUILDING 0% completed
kompak#

...and after the message it gets stuck on 0% probably because it never
started rebuilding in the first place?
