Tor Harald Thorland was having trouble with a USB disk.

Hooray. You have nailed down the problem to the ACPI subsystem.

Hmm. I suspect we can get the USB mouse to work later.
What happens if you turn off quiet and rhgb in the kernel command line
(the same place you put the acpi=noirq)? It will still hang, we just
might get to see what's causing the hanging.

Manufacturer differences. Some put a partition table on their USB disks,
as though they are hard disks, and you get sda1. Others don't, as though
the disks are floppies or CDs, and you get sda.
Persons with sufficient spare time may experiment with partitioning CDs
and not partitioning hard disks. The end results should work in Unix-
based systems, but the rest of the world will probably get horribly
confused.

That's the removing rhgb I was talking about earlier.

Yes please.
Visit bugzilla.redhat.com, specify the kernel as the component cauing
you grief.
One other thing to consider: I don't know if your laptop supports APM,
the older equivalent. You might investigate turning ACPI off
permanently, which should enable APM. You'd then have to configure the
laptop to use APM to do laptop-style stuff like power management and
suspend. I can't really help you there.
