You've got the pirq setup from hell. Mind doing that "dump_pirq" thing, preferably run on an _unmodified_ 2.4.0 kernel (ie none of my test-hacks) or on a 2.2.x kernel (that doesn't even _try_ to do any routing at all - or you can get the same effect by just making "set_sis_pirq()" always just return 0 without doing anything)?

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

You've got the pirq setup from hell. Mind doing that "dump_pirq" thing, preferably run on an _unmodified_ 2.4.0 kernel (ie none of my test-hacks) or on a 2.2.x kernel (that doesn't even _try_ to do any routing at all - or you can get the same effect by just making "set_sis_pirq()" always just return 0 without doing anything)? I don't want to get quantum effects of the observer changing what is being observed.. | 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. Not any better. The thing just moves around, it seems. I'll think about this, and try to find the SiS irq routing register spec somewhere..
