From: garloff@suse.de Subject: Introduce own timeout for TEST_UNIT_READY Reference: SUSE41689 In error recovery, a SCSI device may need more than the 10s SENSE_TIMEOUT to respond to TEST_UNIT_READY, as reported in novell bugzilla #56689. The patch introduces an own timeout for TEST_UNIT_READY which is set to 30s and used.
