Address or Write Phase Parity Error Detected

Hi,

I'm seeing the following errors intermitently:

scsi0: Host Status: Failed(0)
DevQ(0:0:0): 0 waiting
DevQ(0:2:0): 0 waiting
scsi0: Address or Write Phase Parity Error Detected in DFF0.

followed by the card dump (included below). The drives pause for around 5 seconds, and then everything resumes ok. This is with:

Tyan S2469 Motherboard
Onboard Adaptec AIC7902 adapter
Maxtor Atlas 15k 36gig drives

I've tried both the 2.4.26 and 2.6.7 kernels and also the latest aic79xx drivers from:

http://people.freebsd.org/~gibbs/linux/SRC/

but still get the same problem. It seems to happen on heavy disk usage.

The only clues I've found in the archives and online seem to indicate it might be another pci device causing the problems, but I can't seem to isolate what it is (this is a server with no other pci cards, and pretty much everything disabled in the bios that isn't used). I've included below the output of lspci -v -v in case it's helpful.

Does anybody have any ideas what might be the problem? I'd also be willing to pay for some consulting time to help track this down. Email me off list for info.

Here's the card dump:

Hi,

Following up to my own post. This error turned out to be a problem with amd760mpx chipset not being stable at 66mhz, even with no other pci cards installed.

The solution was to jumper the tyan s2469 boards pci bus back down to 33 mhz and we haven't seen the error since.

Cheers,

Alex
