I just cvsupped Justin's tweaks and rebuilt.

During the bootup process, it probes my first 3 devices (2 hds, 1 jazz drive)
then locks up with a white cursor and fails to probe the 4th (a toshiba
cdrom).

My configuration is a 
P5-90/Neptune chipset
3c509
AHA2940U
FreeBSD is on my scsi drives

I have tagged queuing enabled.  I am planning to disable that to 
determine if that is causing my problems.

FYI for those adventure some users :)

below is my normal boot (actually, booting from a slightly older
kernel than my last sup 3 days ago which worked as well)
