>Description:

I have problems boot my PC after installing FreeBSD-2.2-ALPHA.
FreeBSD-2.2-961014-SNAP worked fine (though it took several minutes to boot).

I am puzzled about how the boot disk for 2.2-ALPHA could work and install
the software (from ppp on sl0), but booting from HD is not possible.

Below a screen dump of the boot process (as much as I could catch) 
- it should tell what hardware I have. The CD-ROM that it never find is a 
TEAC SCSI CD-ROM 56S.

Responsible-Changed-Why:  
Looks like an install problem during an upgrade, although 
you might want to re-assign this to Justin instead, since 
it is a SCSI related failure.

State-Changed-Why:  
I think this was one of Justin's transient SCSI driver problems. 
Please test again with the latest GAMMA from 22gamma.freebsd.org 
and let us know if the problem is still open.
