Hmm,
from reading what people have debugged so far, this looks like a problem
with the Asmedia ASM1083 PCIe-PCI bridge:
http://marc.info/?l=linux-kernel&m=132793745319418
and both Intel and AMD boards which are integrating this thing are
affected.
There's even a great message from Asmedia at the end of the thread, it
is a lot of fun reading.
As always, I'll try to ask around but can't promise anything. We
probably need to get some Intel folk involved too.
@Müller: can you send me the mail address of that Asmedia contact
privately? If ASUS are on CC, them too.
Thanks.
