From ce560dcf20c14194db5ef3b9fc1ea592d4e68109 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Tue, 31 Jul 2012 11:28:26 +1000 Subject: ATAPI: STARTSTOPUNIT only eject/load media if powercondition is 0 The START STOP UNIT command will only eject/load media if power condition is zero. If power condition is !0 then LOEJ and START will be ignored. From MMC (sbc contains similar wordings too) The Power Conditions field requests the block device to be placed in the power condition defined in Table 558. If this field has a value other than 0h then the Start and LoEj bits shall be ignored.
