Re: aic7xxx broken in 2.6.18-rc3-mm2

[Dave Hansen <haveblue@us.ibm.com>]

Well, I have a new culprit of the hour:

	gregkh-pci-pci-use-pci_bios-as-last-fallback

There was a previous patch that messed up a few of my machines and this
same driver a few months ago, which accounts for my sense of deja vu:

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc6/2.6.16-rc6-mm1/broken-out/gregkh-pci-pci-give-pci-config-access-initialization-a-defined-ordering.patch

There was an off-list thread called 

	"PCI device issue in 2.6.16-rc3-mm1 through 2.6.16-rc6-mm1"

Anyway, here's the information from the syslog at boot in a working
system (without the patch applied):

PCI: PCI BIOS revision 2.10 entry at 0xfd32c, last bus=8
Setting up standard PCI resources
SCSI subsystem initialized
PCI: Probing PCI hardware
PCI: Discovered peer bus 02

And the same thing in a system where it can't find my SCSI card (with
the patch applied):

PCI: Using configuration type 1
Setting up standard PCI resources
SCSI subsystem initialized
PCI: Probing PCI hardware
PCI->APIC IRQ transform: 0000:00:05.0[A] -> IRQ 16
PCI->APIC IRQ transform: 0000:00:0f.2[A] -> IRQ 19
