>Description:
My HP Pavilion a430n hangs at "ubub2 at usb2: vendor 0x10de EHCI root hub, 
class 9/0, rev 2.00/1.00 addr 1" using NetBSD 5.0 CD. I have successfully 
installed NetBSD 4.0.1 on the same machine. Booting without ACPI, or without 
ACPI and SMP, has the same result.
>How-To-Repeat:
Boot an HP Pavilion a430n with the NetBSD 5.0 installation CD.
