Artem, thanks for your Help. FYI, the ENXIO is caused by sd_send_scsi_TEST_UNIT_READY returning EIO.
If anyone knows more about the speicific implementation of the Option pseudo CD Reader, please let me know. At least this does not seem to be a general pcmcia issue (except for the pm deadlock, but that's not in the way right now) -- This messages posted from opensolaris.org
