Okay, I've managed to get the debug kernel built and save the core file.
I'll include the output of some basic debugging below. If there's anything
else that would be helpful, let me know. The D-Link driver disk includes C
source for a Linux driver, so when the problem gets narrowed down, I or
someone more familiar with the code might be able to use this to determine
the correct settings.
First, though, I should have included this before, but I didn't notice it
until much later. Here's an excerpt from the boot messages that gets shown
before the crash. During a GENERIC boot:
pci0: <unknown card> (vendor=0x1186, dev=0x1300) at 11.0 irq 11
During my customized boot (I think this is right, but had to write it down
and type it in, so there may be minor errors) this turns into:
rl0: <D-Link 8139 10/100BaseTX> port 0xd800-0xd8ff
mem 0xe5800000-0xe58000ff irq 11 at device 11.0 on pci0
rl0: Ethernet address xx:xx:xx:xx:xx:xx
miibus0: <MII bus> on rl0
rlphy0: <RealTek internal media interface> on miibus0
rlphy0: no media present
It then proceeds through the normal boot sequence to the crash. Here's the
gdb log I threatened above. Warning: it's long.
