Hello,

after a walk through the module "io_apic.c" in
"/usr/src/linux/arch/x86/kernel/apic" I got the impression that the
variable "nr_ioapics" is used but isn't initialized !

Just to be sure we are looking at the same thing, it is declared in
arch/x86/kernel/apic/io_apic.c on line 129.  Being declared that way,
it is, by definition, 0 unless there is an initializer.

Did I miss something?

Thanks,
Robin

Could it be the source of boot problems ?

Dangerous coding stile in "static struct resource * __init
ioapic_setup_resources(int nr_ioapics)" ....
