+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: dasd: DASD uevents are not sent correctly
+References: bnc#440610,LTC#49429
+
+Symptom:     by-id device links are not created
+Problem:     On SLES10 there was an extra patch that would send
+             uevents for a DASD block device when it reached the
+             online state. This code was never upstream and is now
+             missing from SLES11.
+Solution:    Send change events when device reaches or leaves online
+             state.
