+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.
