system hang on boot w/ "atapicam0: timeout waiting for ATAPI ready" (5.1-CURRENT, IBM T30)

[Lee Damon]

As reported on Fri, 05 Sep 2003, I am seeing a hang on boot when I
have the CD-RW/DVD installed in my T30's ultrabay.  When I remove
the drive the system boots fine.  Having a CD in the drive does not
help.  The system hangs hard enough that I have to hit the power
button to get it's attention.

Is anyone else seeing this?
