When using the on-board AIC-7890 controller on a ASUS P2B-DS I sometimes got some strange boot problems (when performing the interrupt driven probing of the scsi bus): ahc0: brkadrint, (null) at seqaddr = 0x17d ahc0: brkadrint, (null) at seqaddr = 0x17d ahc0: brkadrint, (null) at seqaddr = 0x17d ahc0: brkadrint, (null) at seqaddr = 0x17d ahc0: brkadrint, (null) at seqaddr = 0x17d .... ahc0: brkadrint, (null) at seqaddr = 0x2 ahc0: brkadrint, (null) at seqaddr = 0x2 ahc0: brkadrint, (null) at seqaddr = 0x2 ahc0: brkadrint, (null) at seqaddr = 0x2 ahc0: brkadrint, (null) at seqaddr = 0x2 .... Instead of information about the real hard error, (null) was printed. The error code read from the ERROR register was DPARERR (0x10). As a workaround, I'm using a lower value for the PCI latency timer (configured in the Mainboard BIOS). I also had to modify the driver to ignore left over BIOS settings, since the driver gave unreasonable values for transfer rates when attempting to use the left over BIOS settings. - Tor Egge To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
