I think that's determined by drivers/scsi/sr.h::SR_TIMEOUT which is
hardcoded to be 30 seconds.  Maybe it's better to move it to use the
block parameter.  Anyways, the drive actually takes longer than 30secs
to recognize the media?

That slow behaviour is not uncommon, especially as drives struggle
to recognize various forms of copy-protected media (DVD-Video).
A longer default, or tuneable timeout, would help.
