OTOH, the accounting hook would allow us to remove the IRQ#0 -> CPU#0

Some SIS chipsets hang the machine when you migrate irq 0 to another
CPU. It's better to keep that Also I wouldn't be surprised if there are some
other assumptions about this elsewhere.

Ok in theory it could be done only on SIS, but that probably would really
not be worth the trouble


I just got a x8664-hrt report, where I found the following oddity:

 0:       1197     172881   IO-APIC-edge      timer

That's one of those infamous AMD C1E boxen. Strange, all my systems have IRQ#0 on CPU#0 and nowhere else. Any idea ?


Here I have with stock FC7 ( kernel :
0:     107835  133459760   IO-APIC-edge      timer

vendor_id    : AuthenticAMD
cpu family    : 15
model        : 107
model name    : AMD Athlon(tm) 64 X2 Dual Core Processor 4000+
