   1 From: Gerald Schaefer <geraldsc@de.ibm.com>
   2 Subject: Fix unsolicited SIM sense condition.
   3 References: bnc#458339
   4
   5 Symptom:     SIM reported via unsolicited interrupt are not shown.
   6 Problem:     SIMs are alway 32 bit sense data so byte 27 bit 0 has not to
   7              be set. This was mixed up.
   8 Solution:    Negate condition for byte 27 bit 0.
