hi,

i built a kernel with APIC_IO and SMP for my p4 with hyperthreading. 
when i try to boot the kernel it hangs during boot at:

APIC_IO: Testing 8254 interrupt delivery

doing

while (read_intr_count(8) < 6)
	;   /* nothing */

(sys/i386/isa/clock.c:1030)

read_intr_count(8) returns 0 forever...

i dont know how to provide a dmesg as i cant get to a shell. this 
computer is a laptop with sis 645dx chipset.

anyone have a fix for that?

regards,
bernhard
