Replying to [comment:22 korli]:
ACPICA tries to update io-apic routing for this device but fails (I
don't know what to do with this):
KERN: failed to update interrupt_line for PCI 6:4 mask 1
This has a function mask of 1 (function 0, mask = 1 << 0), but I'm
interested in function 4 (mask 10 = 1 << 4).
Here is a larger extract of the log with all the functions provided by
this device:

Function 0 (which corresponds to mask = 1) does not seem to have an
interrupt attached to it at this point. Functions 3 and 4 have one
interrupt each (not the same one).
And the interrupt table is this:
{{{
KERN: address 0x4ffff; pin 0; GSI 16; pci 6:4 pin 1 func mask 1; bios irq:
10; gsi 16; config 0x06
KERN: address 0x4ffff; pin 1; GSI 17; pci 6:4 pin 2 func mask 8; bios irq:
10; gsi 17; config 0x06
KERN: address 0x4ffff; pin 2; GSI 18; pci 6:4 pin 3 func mask 4; bios irq:
11; gsi 18; config 0x06
KERN: address 0x4ffff; pin 3; GSI 19; pci 6:4 pin 4 func mask 10; bios
irq: 10; gsi 19; config 0x06
}}}
Now I don't understand why function 0 (mask 1) has an interrupt listed
here, while in the previous part of the log, it didn't. But I'm not very
familiar with PCI, is that expected?
