Well, not exactly this line (0000:00:11.1 is the IDE controller, which is
in legacy mode and therefore does not use its PCI interrupt), but the next
similar line is for the USB 2.0 (EHCI) controller:

-PCI: Via IRQ fixup for 0000:00:10.3, from 5 to 10


Try as root:

setpci -s 00:10.3 INTERRUPT_LINE=0a

(this matches "ehci_hcd 0000:00:10.3: irq 10, ..." in dmesg).

If after doing this USB works again (you will need to replug USB devices),
the missing VIA IRQ quirk is definitely the problem.


You seem to have also the builtin audio and Ethernet on this board - these
devices may have the same problem, if you tried to use them.
