PCI Bridge problems

From: David Lewis (dlewis@vnxsolutions.com)
Date: Wed Jul 09 2003 - 22:47:24 EST


Greetings,

I am running into a problem with some PCI cards and I believe I have it
narrowed down to the fact that they have PCI-PCI bridges and they dont seem
to be agreeing with the kernel (2.4.18, 2.4.20, 2.4.21-ac4).

The cards are a Adlink PCI-8214 dual ethernet nic (Intel 82559 eth
controller and 21154 pci bridge) and IDS imaging Falcon quatto (4 Bt878
frame grabbers and a ethernet bridge). Both cards work well with 2.4.18 in a
motherboard with a single pci bus (Tyan Tiger 200 Apollo Pro 133A dual P3),
but when used with an Intel SE7500CW2 Dual Xeon (multiple pci busses) they
become very flaky. My suspicion is that the busses are not being recognized
correctly, but everything does show up in lspci.

Following is the lspci and dmesg output. Please let me know what further
information I can supply.
