In bug 7547[1], somebody is issuing START_STOP to the ODD repeatedly which times out if the drive is empty. Is this coming from PKTCDVD or from userland polling? Also, do you mind adding yourself to the bug so that I don't have to relay? Thanks. -- tejun [1] http://bugzilla.kernel.org/show_bug.cgi?id=7547
