	Well, I'm not sure if anyone else ahs run into this, Bbut here's the
problem...
I have an IBM ThinkPad 760EL (P-133, 80MB RAM). I loaded the full 1.5Alpha2,
while it was out of the IBM DockStation II. Runs great. When I booted it up
in the Dock, it got to:

"scsibus0: Waiting 2 seconds for devices to settle..."

and never continues. When I pulled it out, it booted fine.

Is this a known problem?
Do I need to file a problem report?
Something else I can try/do?

-> tape drive, etc...), two ISA expansion card slots, and a second Type
