Hi all.
I've been running 3.x-stable on a firewall box for months and months, and it's
been very, well, stable :=)
Recently, it's started intermittantly (every week or so) giving problems like the following (somewhat
trimmed) output:

At this point, rebooting is really the only option.
Hardware is an Intel 430VX chipset with a 233MMX CPU fitted, 32Mb true parity memory, and two PCI NIC cards,
along with a TekRam DC-390 F (I think, AMD 53c875 chipset, anyway) SCSI card. Here's the dmesg output:

Errr, what's going on? Is this a hardware problem (the boot/swap drive is a slow old
Fujitsu 500Mb drive, which always seemed to work fine before), or something wacky with
either CAM or the NCR support?
I can happily replace the hardware, but if there's anything that should be done to identify
some weird problem, I'd be happy to help out as best I can (like providing access, additional
information etc).
Cheers,
