It has multiple hardware defects involving ATA request-size handling (SIIBUG in 
ata_sii_allocate() in dev/ata/ata-chipset.c around line ~2300 of the FreeBSD 
driver, or what the Linux guys call SIL_QUIRK_MOD15WRITE in their sources), and 
there seem to be problems with LBA48 mode if used with various Seagate drives 
bigger than ~143GB.

I've also gotten the impression that the chipset is prone to locking up the
entire system under some circumstances, especially under RAID-1 mirroring or 
other parallel access cases, because it mishandles interrupts under high load.
