FYI:
My system config is one 400GB disk at sda, and two 250GB disks on a dmraid
nvidia-fakeraid set of sdb and sdc.
My kernel message buffer gets quickly overrun by a flood of these error

p.s:
Why does the kernel report a queue depth of 31/32, but hdparm says its 32? Is
this correct?
ata1.00: ATA-7, max UDMA7, 781422768 sectors: LBA48 NCQ (depth 31/32)
