Here is what my system is telling me.

twe0: unexpected status bit(s) 800000<PCIPERR>
twe0: PCI parity error: Reseat card, move card or buggy device present.

Here is what I am running.

FreeBSD 4.7 p25
boot disk IDE
SCSI tape drive
twe0 is an Escalade 7500-4
twe1 is an Escalade 7000-2

I have tried two different 7500-4 cards.
I have changed slots.
I have tried 3 different motherboards.
	1 MSI K7 Master-S

What I suspect.

The Escalade 7500-4 is a 64 bit card.  I am using it on
a 32 bit bus.  The manual doesn't say you can't but I am
suspicous.  Both 7500-4 cards worked just fine on Linux
and Windows on both 32 and 64 bit motherboards IIRC.

Is it possible we have a driver issue here?

The machine is a backup server so reliability is important. :^)
So far I haven't lost any data but......

If you can help great. If you need more info let me know.
