+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: Fix unsolicited SIM sense condition.
+References: bnc#458339
+
+Symptom:     SIM reported via unsolicited interrupt are not shown.
+Problem:     SIMs are alway 32 bit sense data so byte 27 bit 0 has not to
+            be set. This was mixed up.
+Solution:    Negate condition for byte 27 bit 0.
+
+Acked-by: John Jolly <jjolly@suse.de>
