Booting with maxcpus=0 also disables the I/O APIC, which probably is a bit too
much, but let's see what happens in that case.

Well the only-booting-with-nolapic one doesn't boot with maxcpus=0. Pff, 
are there any compile-time(Kconfig) or runtime parameters related to 
debugging various subsystems that you'll suggest which will show where 
the boot hangs? That way we can maybe pinpoint the issue to a specific 
function call.

Booting with initcall_debug causes all of the initcalls to be shown (start,
finish and duration), so it may allow you to find the culprit if you can
collect the messages.
