Good...

It looks like a problem with network interrupt routing. I don't know why
since it works on my 2600 which use the same interrupt for the de4x5.
Can't test on a 2400 for now, sorry...

What does 'cat /proc/interrupt' tell, as well as /proc/ioports and
/proc/iomem ?

In which PMC slot did you put the Ramix (upper or lower ?). IDE interfaces
have strange interrupt routing topologies (and give me a _sane_ interrupt
system, a la VME or even Z80, any day :-().

Not for now...

Ok, reconfiguration of Hawk in CHRP mode.

Fine (although IDE is a mess with registers spread all over the place,
especially the WinBond)

Wow, my biggest machine has 32 Mb :-(

Set CONFIG_RTC and/or CONFIG_NVRAM off. They don't work properly in any
case on this machine...

Looks again like interrupts are not coming through, or are set edge
instead of level or whatever.
