I think the ACPI issue is a red herring. I didn't realise it was enabled
when I built the kernel and was surprised when I found it trying to share
an IRQ with the network card. It's not enabled any more, but the card
still doesn't work :(

I'm retyping this from the screen, since I can't get onto it over the
network. I've checked for errors and don't see any, but you know how it
is...
With 2.2.14, I get:
0: XT-PIC timer
1: XT-PIC keyboard
2: XT-PIC cascade
7: XT-PIC soundblaster
9: XT-PIC eth0
10: XT-PIC aic7xxx
11: XT-PIC bttv
12: XT-PIC PS/2 mouse
13: XT-PIC fpu
14: XT-PIC ide0
2.3.33 gives me:
0: XT-PIC timer
1: XT-PIC keyboard
2: XT-PIC cascade
7: XT-PIC soundblaster
9: XT-PIC eth0
10: XT-PIC aic7xxx
11: XT-PIC uhci, bttv
12: XT-PIC PS/2 mouse
13: XT-PIC fpu
14: XT-PIC ide0
As far as I can ascertain, under Win98, I have:
0 timer
1 keyboard
2 interrupt controller
3 COM2
4 COM1
5 Maxtrox G200 and Hollywood Plus MP3 decoder
6 Floppy controller
7 Soundblaster 16
8 Clock
9 3c509
10 AHA2940
11 WinTV and PCI/USB controller
12 Mouse
13 FPU
14 Primary IDE Controller
15 Secondary IDE Controller
I see arp requests from the machine on the network, and I see responses from
the remote systems to those requests. Clearly the kernel doesn't see them
though, and the IRQ count as displayed in /proc/interrupts never gets
above zero.
I'm building 2.3.39 as I type, but I don't hold out a whole lot of
hope for anything different. After that I'm going to start pulling boards
out until the card starts working again, but I don't think that's going to
help me understand the problem much, nor to fix it. If it didn't all
work under win98, I'd assume there was a hardware problem of some sort and
indeed that could still be the case. I just don't know how to move forward
with this now.
James.
