SCSI guys,
kern/103602 is a long-standing issue with a Sony DVD drive that has a
strange behaviour (failing to attach and causing an interrupt storm).
One aspect of this PR was that an ATAPI command timing out was not
correctly reported by the ATAPI/CAM SIM to the XPT layer. This has been
fixed in atapi-cam.c rev. 1.49.
Now we have a second issue: if there is no disc in the drive, it
times out a READ CD CAPACITY (and any subsequent retry, even if a disc
is then inserted in the drive), instead of returning an appropriate
error (the expected behaviour would be a NOT READY sense key and a
MEDIUM NOT PRESENT ASC). A TEST UNIT READY command seems to behave
properly (reporting the appropriate error if no disc is present,
reporting no error and resetting the drive to a proper state if
one is).
The timeout causes the unit to fail to attach at boot time if no disc is
present. How should we deal with this situation? One possible option is
to make sure that we first issue a TEST UNIT READY at attach time prior
to issuing READ CD CAPACITY, and not issue the second command if the TUR
returned a NOT READY status.
The traces below show how the drive behaves in response to TEST UNIT
READY and READ CD CAPACITY in various cases. Complete boot messages are
available in the PR history.
Thomas.

Exactly, it appears to work with a cd in the drive, and I get a
transient cd0 dev entry without the disc. Below is the output from
each command you requested. I got a timeout in the last read capacity
command, even after the prior steps. I sent a TEST UNIT READY command,
then it worked, though.
