I am sory, I meant the datasheet of the Au1500. I do not find the 
paragraph anymore, but can tell you more on monday.
One interesting paragraph is "AMD Alchemy Au1500 Processor Data Book" - 
4.3.10 "Other Notes" first paragraph.

The note I meant descibes a situration where a delayed read transaction 
on a pci device behind a pci-pci bridge can cause to a racing condition, 
where the whole system stalls. The CPU does not get the chance to do 
anything anymore, because the PCI subsystem blocks it.
