[PATCH] i386: run BIOS PCI detection before direct

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



from 2.6.16-rc3-mm1 through at least 2.6.16-rc6-mm1 a patch from
Andi Kleen, titled

        x86_64-i386-pci-ordering.patch

which is now called:

	gregkh-pci-pci-give-pci-config-access-initialization-a-defined-ordering.patch

has caused a 4-way PIII Xeon (non-NUMA) to stop detecting its SCSI
card.  I believe this is also the issue keeping -mm from booting
on "elm3b67" from http://test.kernel.org/. 

The following patch reverts the ordering of the PCI detection code
to always run the BIOS initialization, first.  As far as I can
tell, this was the original behavior, and it makes my machine boot
again.
