ahd driver & Adaptec 39320D Ultra320 SCSI adapter

[Sander Smeenk]

Hi,

I mailed to fbsd-questions about a weird problem i was experiencing with
RAID10 on vinum, with 4 SCSI disks connected to an Adaptec 39320D U320
SCSI adapter, and stated that it had boot problems, but they seemed to
occur only at boot, not during usage.

I was wrong. The card is unstable in FreeBSD 4.9-release. Not only does
the SCSI interface timeout on occasion, vinum also seems to crash the
entire system with a kernel panic.

I googled on "pci error interrupt" "card was paused", but no helpful
results turned up. Is anyone aware of this problem? Who should I contact
to report this, or does anyone know what the solution for this problem
is?

I'd really like to get it fixed. Let me know if you need more
information regarding this matter.

Below are some relevant parts from dmesg, during boot:

| ahd0: <Adaptec 39320D Ultra320 SCSI adapter> port 0x7000-0x70ff,0x7400-0x74ff mem 0xfc200000-0xfc201fff irq 10 at device 1.0 on pci3

[ .. later on in the boot process .. ]
