I guess that the reason for the messages is that the kernel tries to
drive the disks too hard and they (or the controller) complain and
the kernel then reduces the transfer mode or whatever to a lower
level. Saw the similar with Promise Ultra100TX2 and SoftRAID5 on 4*60G
IBM drive, when I put heavy load on the not yet synced RAID.
