While trying to figure out why one of Alan's laptops didn't like certain
resource allocations, it dawned on Ivan and me that the PIIX4 (aka
"82371AB PCI-TO-ISA/IDE Xcelerator", aka "old venerable Intel core
chipset") actually has a lot more PCI resources that it decodes than the
two big special cases we had been quirking out.
It's an old chipset by now, but it was very very common, so I bet people
still have them around. If doing /sbin/lspci on your machine mentions
something like
Intel Corporation 82371AB/EB/MB PIIX4 ISA
can you please test out this patch and report what it says in dmesg?
I have one that says:
00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02)
I hope it doesn't matter, but I've applied against the 2.6.13 kernel I
had there at hand (I'm accessing it remotely).
`dmesg -s 1000000 | grep PIIX4` just shows:
PCI quirk: region 4000-403f claimed by PIIX4 ACPI
PCI quirk: region 5000-501f claimed by PIIX4 SMB
PIIX4: IDE controller at PCI slot 0000:00:07.1
PIIX4: chipset revision 1
PIIX4: not 100% native mode: will probe irqs later
