Also it failed at sendmail.fc or something, I don't use send mail so I
just did not build it. It looks like someone already reported the
device apic problem. I just tryed option smp and device apic on my
single proc athlon, panic on boot unless I chose no apic or is it no
acpi(?) at boot.
No ACPI is what you can choose at boot. Can you post the panic message?
By the way, why adding the smp options do any good for my machine? I
mostly care about speed, but it seems it might just make the os unstable
for me.
You can always compile a custom kernel without SMP if you wish. device
apic can be helpful because PCI devices do not have to share interrupts.
Enabling SMP in GENERIC means that SMP machines now work out of the box.
It also means that a sysadmin can use one kernel across both UP and SMP
machines in a hetergeneous environment which can ease system
administration in some cases.
I like the idea of not sharing irqs. Can I have apic without smp on?
Thanks,
Jason
