Comment 1 Thomas Meyer 2009-07-08 15:54:19 UTC 
Looking at the commit between 2.6.31-rc1 and current master: Try reverting commit 018e0446890661504783f92388ecce7138c1566d (block: get rid of queue-private command filter).

I gave it a try and reverted above commit. Now the empty CD shows up again.
Comment 2 Thomas Meyer 2009-07-11 14:51:16 UTC 
Fixed by 76da03467a1a78811777561bbb1fa56175ee4778 (block: call blk_scsi_ioctl_init())
