Badness in pci_find_subsys

[Robin Rosenberg]

There is a regular error (2.6.1,2.6.2) that locks up my X although I don't know if it has anything to
do with X per se other than that after every lockup i find an error in syslog.

The stack dump comes out twice with the same time stamp (same in dmesg so I assume the
