Heya,
It turns out the copy of the 2.0.33 kernel source didn't have the flag
to enable the 53c8xx driver for some reason. I got that compiled in and
finding the card, but now it's having trouble fully initiallizing
because it can't get it's own IRQ.. it invariably chooses the one that's
already being used by the Adaptec 2940.
I've played with the PCI BIOS settings, enabling Plug & Play and
changing the IRQ search order, but none of this seems to have any effect
(other than making both cards try to use a different IRQ). I also tried
disabling the shared irq feature in ncr53c8xx.h and passing the various
ncr53c8xx=irqm:? flags to the kernel.
Does anyone know how I might resolve this? I didn't see anything in the
README.ncr53c8xx file or on usenet that seemed applicable.
Here's what i get when i boot (this was after i disabled the shared irq
feature in the source, but was almost exactly the same before that as
well):
