Thanks. This rings a bell, I seem to remember what I thought to be "impossible numbering" on the CPUs such as "CPU7" or somesuch in a dmesg.. Will have to look through logs. I'll raise CONFIG_NR_CPUS and see what I get. Now, the question is, why do we only interrupt on CPU0 on this pasrticular box|chipset with a vanilla kernel? ACPI problem? My SMP G4 ppc has an option in menuconfig: "distribute interrupts on all CPUs by default", the x86 has no such option. Ethan
