I'm on a Thinkpad T41p.  The installer's first screen gets to "Probe hard disk controllers" and freezes there.  The mouse can still be moved, but I can't do anything else but switch virtual consoles.  This happens every time I try to install Alpha3 on this machine.

There was this oops info (copied by hand):
