I'm running FreeBSD 4.3 and 4.4-RC1, and have a Adaptec 2930U2 scsi
card.  After upgrading my mainboard to an Epox 8k7a I've started getting
the following messages (normally at boot time):

Aug 19 21:17:03 ganymede /kernel: ahc0: PCI error Interrupt at seqaddr =
0x8
Aug 19 21:17:03 ganymede /kernel: ahc0: Data Parity Error Detected during
address or write data phase
Aug 19 21:17:03 ganymede /kernel: ahc0: PCI error Interrupt at seqaddr =

0x9
Aug 19 21:23:20 ganymede /kernel: ahc0: Data Parity Error Detected during
address or write data phase

Here's the Adaptec line:

ahc0: <Adaptec 2930 Ultra2 SCSI adapter> port 0xe400-0xe4ff mem
0xdd002000-0xdd002fff irq 11 at device 11.0 on pci0

The only thing on the scsi bus is a Plextor CD-R.  I get the messages at
boot time, and periodically while using the Plextor.

Any ideas?  The Plextor seems to work fine but I am worried about the
messages.  Please CC and reply to my address above; I'm not a member of the
list.

Thanks.
