I checked in a change to the CAM error recovery code that will hopefully
have a positive effect on systems with CDROM drives that were taking a
while to probe.
Anyway, try this out and let me know if there are any regressions.
Thanks,
Ken

Modified files:
sys/cam cam_periph.c
sys/cam/scsi scsi_cd.c
Log:
In camperiphdone(), make sure we check for fatal errors and bail out
instead of retrying them blindly.
This should fix some of the problems people have been having with cdrom
drives taking a long time to probe. This should also eliminate the need
for the initial TUR in cdsize().
cam_periph.c: Don't keep retrying if the error we get back is a fatal
error. This should help us detect the transition from
"Logical unit not ready, cause not reportable" to "Medium
not present" in the "TUR many" handler. (The TUR many
handler gets triggered for Logical unit not ready, cause
not reportable errors.)
scsi_cd.c: Remove the initial test unit ready in cdsize(). Hopefully
it isn't necessary after the above change.
