OK, I finally have a theory about this. It's the everything goes via bios code. Previously there were several levels at which commands could exit the SCSI stack; now we make everything go via bios, so they all come out at the top. get_capabilities() in sr.c is sending a TEST_UNIT_READY which will get NOT_READY back. Previously this was completing before it got to scsi_io_completion(); now it doesn't. There must be quite a few cases like this. The best fix is probably to use and respect REQ_QUIET for internally generated commands.
