PCI/ACPI related boot hang with 2.6.0-test5-bk3 on KT266A mobo

PCI/ACPI related boot hang with 2.6.0-test5-bk3 on KT266A mobo

[Jeffrey Layton]

I seem to be having a problem booting my main home machine with the
2.6.0-test5 kernels. I'm able to boot it with the flags 'acpi=off',
'acpi=ht', or 'pci=noacpi', but without one of these, it hangs just
after outputting this line:

mice: PS/2 mouse device common for all mice

The problem is easily reproducable. It hung with the stock -test5 kernel
and with -test5-bk3. 2.4.22 doesn't seem to have this problem. I am
using the binary nvidia module, but the problem occurs before it gets
plugged in. When the hang occurs, the magic sysrq key doesn't respond,
so I don't have much info to go on.

The machine in question has a Epox 8KHA+ motherboard with 1G of memory.
It has a VIA KT266A chipset.

I'll happily provide more info or test patches for this if you can tell
me what you need. As I'm not a LKML subscriber, please reply to me
directly.

I couldn't get the patch to apply cleanly, so I applied it by hand. It
does seem to fix the problem in test5-bk7. Many thanks!
