Hello,

	The gregkh-pci-pci-sparc64-use-generic-pci_enable_resources.patch which
replaces arch-specific code with generic pci_enable_resources() makes my sparc64
box unable to boot (that's what quilt bisection says). At first I see these messages:

hme 0000:00:01.1: device not available because of BAR 0 [1ff80008000:1ff8000f01f] collisions
sym53c8xx 0000:00:03.0: device not available because of BAR 0 [1fe02010400:1fe020104ff] collisions
sym53c8xx 0000:00:03.1: device not available because of BAR 0 [1fe02010800:1fe020108ff] collisions

and finally, infamous

VFS: Cannot open root device "sda3" or unknown-block(0,0)

	Mariusz

PS. I attached .config used at bisection time.
