I'm not sure what PCI breakage you're referring to, but a lot of the
Cardbus-centric "breakage" isn't a regression - it's new machines
with weird PCI BIOS setups being incompatible Linux's current PCI
bus handing strategy.
I've been trying to get this fixed for a considerable time, but linux-pci
folk seem to be disinterested.
The assumption that the PCI BIOS will sanely assign the PCI bus numbers
and that Linux does not need to reassign them is looking increasingly
incorrect - most of the Cardbus "why can't the system see my card"
are resolved by passing "pci=assign-busses", which causes the PCI
subsystem to renumber all PCI busses.
So far, no one who has tried this solution has reported any additional
problems that I'm aware of.
Therefore, maybe that should become the default behaviour?
