I have 2 SMP-Boards and both need noapic. One is from 2001 (AUSUS CUR-DLS), one is from June 2006 (Gigabyte M57SLI-S4). There are many reasons: 1. Bugs which have such a simple workaround don't get much attention. 2. Usually SMP boards are used for machines, which just HAVE to work, since they have been expensive. These are not consumer boards. 3. I usually had only USB problems (no IRQ), if ommiting noapic. USB technology is a cosumer grade technology and enterprise grade developers don't have much interest in it (until now?). 4. IRQ routing setup is often a BIOS issue. You might be able to fix that by upgrading your BIOS. That often needs a Windows tool. Linux people not always (want to) have access to Windows :-) I reported the all the problems (starting 2001), no developer seemed interested. I can report them against the latest RC6 kernel tomorrow and put them into bugzilla, if we now REALLY care.
