Here is /proc/interrupts after the latest irq quirk fixup patch on
2.6.16.21-0.25 (SuSE 10.1)

After much more testing I'm thinking it's a hardware problem with the
SATA ports on the motherboard so they are disabled.

I may go back to an older kernel version to see if it still freezes
using USB, IDE and SATA at the same time.

This is the fixup messages I got before the patch:

<6>PCI: VIA IRQ fixup for 0000:00:0f.1, from 255 to 9
<6>PCI: VIA IRQ fixup for 0000:00:10.0, from 10 to 1
<6>PCI: VIA IRQ fixup for 0000:00:10.1, from 10 to 1
<6>PCI: VIA IRQ fixup for 0000:00:10.2, from 11 to 1

0000:00:10.x are the USB ports.
0000:00:0f.1 is the IDE.

The USB interrupt is the same pre and post patch.

Thanks,

Dyson
