APIC is not in the kernel
I put
__asm__("int $0x2f");
before calibrate_delay and inside as well for testing. spurious 8259A int15 was reported and up to 18000 counted in /proc/interrupts, but no hang ;-)
I suppose have to settle for hardware/BIOS (IRQ misrouted/8259 init problem or timer not working) as the cause for the hang
