Subject"Badness in pci_find_subsys"
Kernel version: 2.6.0-test1
CPU type: x86-64 (Opteron)
PCI information attached.

I get: Badness in pci_find_subsys at drivers/pci/search.c:132 comming from
2 different things(one seems to be from the tg3 ethernet driver and the
other from the ide driver), I also attached the exact call trace (before
the pci information).
