Do you have one of those systems to hand? My betting is on that when you
enable APIC/IOAPIC you will see crashes very frequently. This isn't enabled in
the default kernel config..

PS, Ross: Again, great work, thanks. I am running the patches you posted in
the thread starter (without the previous ones) on 2.6.3-rc2-mm1 without problem.
