I just built a kernel from a very recent SUP of -current and when I boot
it, it no longer probes my Yamaha CD-RW drive correctly.  Besides that,
it comes up with strange sync values for the other drives, such as
20.83MB/s for my fast/narrow IBM drive.  All my SCSI devices are driven
from the DEC 3000/300 built-in SCSI controller.  Has anyone else
experienced this?  I like using my CD-RW drive, so I hope this isn't a
permanent "fixture..." :-)

Here is the dmesg output from the recent kernel:

Also, why did it go from 1.5.1 to 1.5Q?
