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=20
boot time would be nice :)

Is it possible to disable the i8254 timecounter? On every system I own (and=
=20
these are all quiet old) evryone uses the ACPI timecounter, and there's=20
TSC left... So is anything speaking against making i8254 an option in the=20
kernel config? Or is it needed for basic IRQ operation?

Thanks,
