OK, test done. I first verified I still couldn't blkid or mount with the cdrom_id rules enabled (since a lot of updates have been occurring) and I couldn't, so I disabled the rules and rebooted and was able to blkid/mount. Then I ran the trace you requested, but was still able to blkid/mount after them (I think we were hoping I wouldn't be able to). I've attached the trace and kernel log.
