SubjectPCI bridge setup error in linux-2.4.x (anyone of them)
I ahve a PC box at hand, which ist containing 8 PCI slots.
Four of them are sitting behind a PCI bridge.
The error in the new kernel series is that during the
PCI bus setup if a card is sitting behind the bridge, it
will be miracelously detected TWICE. Once in front of the
bridge and once behind the bridge. The initialisation of
the card will then be entierly hossed.

oops:~ #
doesn't happen under linux-2.2.x kernel series.

Here is the output of lspci on this box after I moved the
