XP1000 questions

> I have problems with various 2.4 kernels on my XP1000 (MONET, 500MHz)
> under RH7.1. As soon as I run 2.4 kernels taylored to the hardware,
> instead of the stock 2.4.3-12 (which does not support all XP1000
> features), a floppy or soundcard access locks the machine, or e.g. the
> ethernet adapter doesn't respond. This happens with all kernels from a
> recompiled 2.4.3-12 (the stock RH7.1) up to 2.4.9 (the latest tested).
> 2.2.19 kernels with identical configs run flawlessly, so I am inclined to
> think that the hardware is ok. By fiddling with the config, I figure that
> sound or XFree support might be the problem, or that the interrupt
> handling is broken.
> Is this a known XP1000 issue, or am I just missing something? Could
> somebody with a working 2.4 kernel on an XP1000 provide me with a kernel

> Another question: A RAM upgrade from 256MB (4 banks of 64MB) to 512MB (8
> banks of 64MB) should double the memory bandwidth on Tsunami chipsets (256
> instead of 128 Bytes per bus access). But what happens when I add 4 banks
> of 128 MB to get 4 banks of 64MB + 4 banks of 128MB (=256+512=768MB)?
> Still 128 bit access, I guess?!
