PCI problem with 2.4.10 on 82434LX chipset

[david]

Hi

 PCI stopped working after upgrading kernel from redhat 2.4.3 to 2.4.10,
ISA devices are fine. Here are dmesg output fragments:

redhat 2.4.3-12:

PCI: PCI BIOS revision 2.10 entry at 0xfd6f2, last bus=0
PCI: Using configuration type 2
PCI: Probing PCI hardware

also lspci output of pci hardware:

00:00.0 Host bridge: Intel Corporation 82434LX [Mercury/Neptune] (rev 11)
        Flags: bus master, slow devsel, latency 32

But using 2.4.10:

PCI: PCI BIOS revision 2.10 entry at 0xfd6f2, last bus=0
PCI: System does not support PCI

Any hope getting PCI bus working on this box? Maybe some hints? Thanx :)

Please try 2.4.10-ac instead

The type-2 config space accesses were broken in 2.4.10 due to an ACPI
rewrite, that got fixed in the 2.4.11-pre kernels (should be fixed in
pre1 already, but you might as well test pre5). 

Most people never noticed, because type 1 tends to be what most machines
use. 

The 2.4.11 kernels are under ftp.kernel.org:/pub/linux/kernel/testing,

Yes, it worked :) I'll try 2.4.11-pre patches too. Thanx again,
