Could SCSI cabling and/or termination cause the card to report *PCI* errors, or am I misunderstanding these messages? I guess that the fact that the "PCI" bit kept showing up in them is what confuses me. I didn't except a SCSI card to report PCI bus issues through the Linux driver, and since it claimed to be a victim, not a cause, I didn't know quite how to trace the problem down...

Adaptec AHA-2940U2W "Data Parity Error Dectected" messages
I recently installed a SCSI tape drive and Adaptec AHA-2940U2W SCSI controller into my server to run backups. Since then, the driver issues these warnings on a semi-regular basis while the drive is busy: Aug 9 17:00:26 anu kernel: scsi0: Data Parity Error Detected during address or write data phase Aug 9 17:00:26 anu kernel: scsi0: PCI error Interrupt at seqaddr = 0x8 [...] Aug 9 17:03:34 anu kernel: scsi0: Data Parity Error Detected during address or write data phase [...] Aug 9 17:04:36 anu kernel: scsi0: PCI parity error checking has been disabled.
