Can you check to see whether there are any BIOS updates available
for your box? It looks to me like your USB controllers are wired
to IRQ9, and that's how the BIOS is leaving them configured.
And if this is a BIOS issue then why it worked for 3 years with all
kernels up to at least 2.6.9
Good point.
Thanks for posting the 2.6.9 output as well. It contains this:
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10
ACPI: PCI interrupt 0000:00:07.2[D] -> GSI 10 (level, low) -> IRQ 10
ACPI: PCI interrupt 0000:00:07.3[D] -> GSI 10 (level, low) -> IRQ 10
PCI: Via IRQ fixup for 0000:00:07.2, from 9 to 10
PCI: Via IRQ fixup for 0000:00:07.3, from 9 to 10
In 2.6.9, we did all the ACPI IRQ routing early, then did the
Via IRQ fixups. In 2.6.11, ACPI IRQ routing is done only when
a driver claims a device, and the Via IRQ fixup is done a little
differently. In fact, the Via fixup happens before we twiddle
the IOAPIC, where in 2.6.9, it happened after.
Can you try the attached patch to see whether it makes any
difference?

Also two more questions:
1. What is VIA fixup? Is it some hardware bug? Or BIOS problem? Why is it
needed? On what hardware / software it is needed?
2. Why this patch shrinked bzImage that much:
-rw-r--r-- 1 root root 1828186 mar 11 23:33 vmlinuz-2.6.11-cko1
-rw-r--r-- 1 root root 1828355 mar 2 20:48 vmlinuz-2.6.11-cko1.old
What is your next guess?
Thanks,
