src/sys/dev/pci: pccbb.c pccbbreg.h
On cardbus configuration reads, check for a master abort in the cbb
and return all-ones explicitely.
Since pccbb.c rev. 1.151 the cbb is set to translate cardbus master
aborts which makes that the PCI configuration read on the primary bus
returns random junk. This can cause the probing code to get confused.
The issue was reported by KIYOHARA Takashi and Jonathan A. Kollasch,
the patch was tested by KIYOHARA Takashi.
