The PCI status reported by the device indicates a PCI parity error.

^bit 0x8000 -> Signaled PCI parity error.
On the other hand, the chip reported a MASTER DATA PARITY ERROR detected.

^DSTAT bit 0x40 -> Master Data Parity Error.
It means that the NCR device detected such an error when acting as a
master, either in some data it tried to read, or the error has been
signaled by the PCI target while the NCR was writing data to that PCI
target.
So, it is not the driver that failed, but the PCI hardware, given that PCI
parity checking is mandatory for PCI-SCSI controllers as we know.
Note that I donnot have any idea about the part that is faulty here. Could
be the PCI-HOST bridge or the NCR device. Your NCR 810 chip is revision #1
and I donnot have errata documents about this old beast. IMO, it would be
interesting to know if some other systems are able to use the current sym
driver with NCR 810 revision #1.
It seems that some combinations of hardware can sometimes trigger spurious
PCI parity errors, notably with NCR/SYMBIOS chips as we can see :). The
usual fix from BIOSes seems to generically not enable PCI parity error
signaling (not set bit 6 of PCI COMMAND register). So, when the PCI
software driver doesn't care of this bit, the PCI device does silently
ignore any PCI parity error it detects (if any occurs). I cannot beleive
that we want to run all our systems with PCI parity checking and
error signaling disabled by default for all PCI devices.
The patch below tries to early detect a possible hardware problem that
triggers MASTER DATA PARITY ERROR conditions and decides to work around
such a problem by disabling the corresponding chip feature.
You may try the patch on your system and let me know.

If this patch detects the problem, but the machine is unstable despite the
disabling of MPEE, then, we should probably also clear bit 6 of the PCI
COMMAND register.
If the patch does not detect the problem, then I will have to find
something better. :(
(May-be the sym driver should disable PCI parity error signaling for old
NCR devices in order to be compatible with other drivers ?????).
