Dan,

Thanks, I have included that code in my kernel and it seems to be
working ok - haven't really tested it yet but at least bus enumeration
works.

This code is based on the PCI 9 workaround for the bug in the 8265,
which uses an IDMA channel for all access. Has anybody looked at doing a
version without the woorkaround? Would it make any difference to the
performance of the system?

Bye for now,
Chris.
