I wonder if the bus numbers for PCI-PCI bridges need to be restored on resume? If they aren't then config transactions won't be routed properly. You could add a pcib_resume() method that prints out the various bus register values after resume to see if they match what we print out during boot. -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
