I'm trying out some new motherboards and I'm getting these errors
when I stress the ATA disk.
ahc0: PCI error Interrupt at seqaddr = 0x9
ahc0: Data Parity Error Detected during address or write data phase
(also had seqadrr 0x8)
This has come up a few times before and seems to be put down to
shared irq's. That doesn't seem to be the case here.
So far I've tried
FIC (1st mainboard) FR133E
QDI Advance 6T
These are both VIA Apollo PLE133T chipset.
I'm running the Adaptec bare, so cables and termination
shouldn't be a problem. Yes?
I was testing with the SCSI drives attached - but I got scared.
I'm testing by doing
#tail -f /var/log/messages&
#time fsck
This gives the error within 3 or 4 runs.
Upgrading from 4.5 RELEASE to 4.6 RELEASE did improve
things.
I know this is cheap hardware, but the Jetway 630CF currently
running has worked fine for a year, and that was cheap too.
I have one more board to try LEX BN630LT.
Of course I have to make a choice *now*.
Here's dmesg for the QDI board.
video irq = OFF
S/C off by jumper
