FastTrack100+2.4.4 panic

FastTrack100+2.4.4 panic

[Eric Olson]

I am having trouble with the 2.4.4 kernel using MSI 694D Pro AR dual
PIII processor motherboard with onboard Promise ATA100.

I have four nearly identically configured motherboards, two of which
have the Promise ATA100 and two which do not.  There are no disks
hooked to the Promise controller and I am not using it.  However, the
motherboards with the Promise controller panic soon after the Promise
detection lines

PDC20265: IDE controller on PCI bus 00 dev 60
PDC20265: chipset revision 2
PDC20265: not 100% native mode: will probe irqs later

with something like a null pointer reference.  I'm sorry not to have
the panic decoded and the message in details.  The 2.4.3 kernel boots
and runs fine on all systems.  The 2.4.4 kernel panics on systems 
with the Promise controller but runs fine on the systems without it.

I'll look at it more tomorrow.  I will be satisfied simply disabling 
the detection of the Promise controller since I'm not using and have 
never used it anyway.  However, I thought this change of behaviour 
between 2.4.3 and 2.4.4 for the MSI 694 Pro AR might be interesting.

Does anyone else have this ideas about this?

The same happens on an MSI 6330 v3.0 (Turbo). I also tried 2.4.4-ac5 which
does not show this behaviour. The ac series have some patches related to
FastTrack/PDC20265, try it out.

BTW, do your MSI boards have a VIA chipset? If yes, do you get any IRQ
conflicts in your dmesg output?

Fixed in 2.4.5pre1/2.4.4-ac

Thanks both Christian Ehrhardt and Axel Thimm!  The two-line patch 
to drivers/ide/ide-pci.c (including comment) worked perfectly.
