When a system running AIX 6.1 TL7 is upgraded to TL8, or AIX 7.1 TL1 is upgraded to TL2, the IPS driver causes the system to crash.
This issue is caused by an IBM kernel defect fixed by the APAR's listed below.
SCSP 5.2.9 MP4 which was released on Dec 13, 2013 does support AIX 6.1 TL8 and AIX 7.1 TL2 if the following IBM iFixes are installed:
AIX 6.1 TL8
AIX 7.1 TL2
