Dear all,

    Concerning my pervious posts about the problem on receiving interrupt
from PCI cards. I guess it is the problem of PCI bridge..(at least I think
it is related).

    Also, under /proc/bus/pci and /proc/pci, I can't see any information
about the brdige.

This is normal.

Also, according to the log you posted bus enumeration was successful and
your device (es1371) was found. So I don't think you have a problem with a
bridge.

FYI, bridge is not responsible for delivering IRQs from your card. IRQ
lines from the PCI slots are directly wired to the UIC (see
walnut::ppc405_map_irq for actual mapping).

According to your log you have inserted card into the PCI slot 1, is this
correct ?

If you still suspect that you have bridge problem, just insert some other
PCI card which is know to be supported by PPC kernel and see...

Also, I don't like these messages "alloc_area_pte: page already exists". It
may be some other problem, though.
