I tested it on a couple of chipsets and it worked everywhere so it should be ok as default for now. So far I haven't done the great purge of the useless old check_timer code yet though. Can be overwritten with enable_8254_timer in the worst case Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds --- diff --git a/arch/x86_64/kernel/io_apic.c b/arch/x86_64/kernel/io_apic.c index f264d9d..db7db1e 100644 --- a/arch/x86_64/kernel/io_apic.c +++ b/arch/x86_64/kernel/io_apic.c @@ -50,7 +50,7 @@ static int no_timer_check; int disable_timer_pin_1 __initdata; -int timer_over_8254 __initdata = 1; +int timer_over_8254 __initdata = 0; /* Where if anywhere is the i8259 connect in external int mode */ static struct { int pin, apic; } ioapic_i8259 = { -1, -1 };
