ahd driver & PCI-X (64bit) Adaptec 39320D Ultra320 SCSI adapter

[Sander Smeenk]

Hi,

I'm having difficulties with my dual P4 server which has an Adaptec
39320D U320 SCSI adapter connected to 64bit PCI (PCI-X). The driver
succeeds to detect the card:

| ahd0: <Adaptec 39320D Ultra320 SCSI adapter> port 0x7000-0x70ff,0x7400-0x74ff mem 0xfc200000-0xfc201fff irq 10 at device 1.0 on pci3
| aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 101-133Mhz, 512 SCBs
| ahd1: <Adaptec 39320D Ultra320 SCSI adapter> port 0x7800-0x78ff,0x7c00-0x7cff mem 0xfc202000-0xfc203fff irq 10 at device 1.1 on pci3
| aic7902: Ultra320 Wide Channel B, SCSI Id=7, PCI-X 101-133Mhz, 512 SCBs

But later on in the boot process, it always 'fails' like this:

| ahd1: PCI error Interrupt

At first I thought this was only at boot, because during normal usage I
couldn't find anything wrong with the controller or disks. But
eventually it started acting up. I tried googling for answers, searched
for 'PCI error interrupt', 'Card was paused' and many more combinations,
but I failed to find any useful information.

Just people who (have?) experience(d?) the same problems, with the same
ahd driver.

Can someone please shed a light on this matter? Things I could try?
I'm lost. I really don't know what to do about this. :|

Sander.
