The controller (which you label in your PR as "some funny RAID
controller") is an Intel 31244:

atapci0: <Intel 31244 SATA150 controller> mem 0xfe1ff000-0xfe1fffff irq 25 at device 2.0 on pci2
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0
ata4: <ATA channel 2> on atapci0
ata5: <ATA channel 3> on atapci0

Some history: this controller was discussed back in 2005:

The appropriate code appears to have been committed to FreeBSD as
of June 2005:

There was a DMA-related fix for this controller committed in February 2006:

Soren, do you have any ideas?
