I would suggest testing jgarzik/misc-2.6.git#master -> vanilla Linux kernel jgarzik/misc-2.6.git#pciseg -> #master + PCI domain support #pciseg + your patch That should narrow down the problems. A problem with aic94xx sorta sounds like something unrelated. > diff -Naurp -X /home/muli/w/dontdiff pci-domains/arch/x86_64/kernel/pci-calgary.c linux/arch/x86_64/kernel/pci-calgary.c > --- pci-domains/arch/x86_64/kernel/pci-calgary.c 2006-09-28 13:31:14.000000000 +0300 > +++ linux/arch/x86_64/kernel/pci-calgary.c 2006-09-28 13:14:38.000000000 +0300 ACK patch - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
