Hi,

I installed a matrox millenium 2 in my C240 box and try to get the
framebuffer device for it to work under linux. Unfortunately I get a
kernel panic at the first access to mmio space of the card. The card
resides in a 32bit PCI slot (it's a 5V only card, so it has to). I get
the impression there is something wrong with the resource assignment of
the card. Unfortunately I'm stuck at this point, since I don't have a
clear view on how all the busses in this system are interconnected and
which bus address translations are happening. Is this somewhere
documented ? Has anyone before succeeded in accessing mmio space of PCI
card attached to the 32bit PCI bus of the C240 ?

Thanks,

Peter.
