Well this is odd. I have the same problem I had with the Pioneer
drive. Namely, it hangs on the INQUIRY. I had to run this for
RELENG_6_2 with the cumulative atapi-cam patch and Scott's new patch
for scsi_cd.c, since I get the mutex Giant not owned panic with my
snapshot of -CURRENT. I'll try cvsup'ing -CURRENT and re-applying the
cumulative atapi-cam.c patch and the new scsi_cd.c patch and see if I
still get the INQUIRY failure.

I had to transcribe this from a digital photo, but here's what I see
shortly after it prints out the hard drives (e.g. ad10, etc):

acd0: cmd INQUIRY status 50 result 00 error 00
