Re: PCI IRQ routing problem in 2.4.0 (SiS results part 2)

[Aaron Tiensivu]

| Which one was it you got a PIRQ conflict for before? as it te device at
| 00:01.00 with the strange "0x62" entry?

Yes.

| How about you try adding the line
| pirq = (pirq-1) & 3;
| at the top of both pirq_sis_get() and pirq_sis_set() (with my "alternate"
| SiS routines). What happens then?

Done.
