I have a multi-port PCI-X card that is causing me some grief. An older version of the system bios allowed this to work correctly, and the on-board devices to work correctly. the newer system bios has fixed a 'bug' where the interrupts were routed incorrectly according to the PCI bridge specification. The system vendor indicates that I am likely missing the support for multiple IOxAPIC, in particular, not supporting the ones in the P64H2 hub. I know that FreeBSD is using the IOxAPIC in the ICH-3 correctly. Can someone suggestion if -stable supports this configuration? I can't get to the point of running 'mptable' since the system won't come up: i get IRQ timeouts on the scsi device. I have a 2x XEON system with ICH-3, e7501, and P64H2. It appears there are two IO APIC in the ICH-3, and two in the P64H2. --don
