Re: SRC B90037FF

IIRC the SRCB90037FF is a generic "Start CPF failed" condition, which effectively requires reviewing the data in the additional reference data to determine the specific failure; i.e. to determine the symptom as origin for the failure-in\diagnosed-by IPL module [named QWCISCFR I think] in the function\subfunction & data of the System Reference Codes. Generally the problem is resolved by reporting the generic failure to your service provider [e.g. IBM] to investigate. However one can, using the following debugged failure as a reference, perform the similar review of the code data with translation of hex data to character data [except failing instruction] to build the symptom string:

From an IPL failure SRCB90037FF, by review of its additional data, the symptom string becomes msgMCH3601 t/QSPFFACB x/174A:

11 B90037FF
13 20A00010 Function\Sub-function /* this is apparently:
Call QSPFFACB to initialize necessary spool file */
14 D8E2D7C6 QSPF
15 C6C1C3C2 FACB ( QSPFFACB )
16 4040174A .. ( x/174A )
17 D4C3C8F3 MCH3
18 F6F0F100 601. ( MCH3601 )

After starting the IPL and before the failure [e.g. by using step mode IPL], one could also review the VLogs and get a dump of the SCPF joblog to get a /prettier/ version of the symptom string and problem origin.

I have a system which keeps getting stuck on SRC B90037FF during IPL. I've done some searches on this SRC and all I've found is
suggestions to IPL again. I've done so and it always comes back.
This is a 170 at v5r3m0. It is one of those double wide boxes.
Any clues on how to fix it?
