Hi,

Since around 2.3.29 or so not all PCI buses in my system are being
traversed properly. Looks like there's a buggy BIOS in the system, but
the devices on all the buses are being found by 2.2.x kernels
nevertheless, as you can see from the output of lspci under 2.2.14
below.

Here's an "lspci --version; lspci -t; lspci -vvvx -H1" for 2.3.52:
