I would disagree
There are five cases I am seeing
1. Serverworks total APIC hose ups. Fix: remove OSB4 or use -ac tree
2. 440BX and similar boards losing interrupts on some drivers Fix: use -ac
3. APIC errors notably checksum errors. Fix: buy properly manufactured hardware
4. Hangs on boot with the CUV4XD and a couple of other boards. Still a mystery
5. Incorrect PCI IRQ routing Fix: Mostly get a board with a correct BIOS. There are a couple of cases people are looking at - some are fixed in 2.4.4 and -ac where magic IRQ lines are not visible directly in PCI space
