Hi, I don't quite follow what the problem with APIC is; but I can tell you my experience with turning it off.
I compiled a kernel without it, and experienced all sorts of random lockups and error messages, such as "spurious interrupt on irq7".
I put it back into the kernel, and the problems stopped.
From the help for APIC in make menuconfig, " the local APIC supports CPU-generated self-interrupts, (such as timers and performance counters) and the NMI watchdog which detects hard lockups.
I have a duron processor.
Mmm. I think the summary of all of this is: - Some people have problems with APIC - Some people have problems without it - Some people find APM doesn't work with it - Some people found soft-halts didn't work with APIC and APM - Some people found soft-halts didn't work in any combination - Some people found it all worked fine in more recent kernels So that's clear isn't it. And it's all the fault of the BIOS of course. Strange that the default kernel on installation comes with it on... Still if you don't mind your disks being reduced to a snail's pace you can always choose the fail-safe option. Anyway, it is all explained in the SuSE Reference Manual on page..errm.. page...strange must be missing from my manual copy. -- Regards Cliff
