Ok. I changed the condition back to the original one and changed the
delay from 1 to 3 seconds.
And it hangs in delay() (arch/i386/isa/clock.c) maybe in gettick() !
This occurs when booting from poweroff.
When rebooting it continues (with some trace output enabled).

Hm. But INSTALL_LAPTOP states:
# Avoid irq 5 and 7, the most likely cause of problems on modern laptops.
options         PCIC_ISA_INTR_ALLOC_MASK=0xff5f
