Strange how the pc-servers numbers are so much smaller. If you hub has
diagnostic lights, also looks at those. I'd verify the base addr
(different from what I'm used to) and irq on the pc-server. Make sure
nothing else is using that irq and that the card is really using that irq.
Then do the same for the laptop. It means pulling out manuals, checking
jumpers, using isapnptools, and loading/unloading kernel modules. I can't
guarantee a hardware problem, but others on the list seem to agree that
it's the first step.
Good luck,
Brandon
