Your dmesg you sent only had

PCI: Via IRQ fixup for 0000:00:11.2, from 9 to 11
PCI: Via IRQ fixup for 0000:00:11.3, from 9 to 11
PCI: Via IRQ fixup for 0000:00:11.4, from 9 to 11

for the Via IRQ fixup, so I assumed that you only had regular ones.

No irq's over 15 according to that (and no, it's not because of the
masking: you also had

ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 11
ACPI: PCI Interrupt 0000:00:11.2[D] -> Link [LNKD] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI Interrupt 0000:00:11.3[D] -> Link [LNKD] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI Interrupt 0000:00:11.4[D] -> Link [LNKD] -> GSI 11 (level, low) -> IRQ 11

in there.

So the patch I sent should in fact have made zero difference at all for
you. What's up?
