Does really nobody know why the machine seems to hang here?
Especially on my laptop I'd love to get rid of this break, 5 seconds less 
boot time would be nice :)

Is it possible to disable the i8254 timecounter? On every system I own (and 
these are all quiet old) evryone uses the ACPI timecounter, and there's 
TSC left... So is anything speaking against making i8254 an option in the 
kernel config? Or is it needed for basic IRQ operation?

Thanks,
