prng.a1d3da The prng module cannot start in SHA-512 mode
Explanation
The pseudo-random number device driver was loaded with the mode= module parameter
or the prng.mode= kernel parameter set to 2. This setting forces SHA-512 mode,
but the required support for MSA 5 is not available. This support requires an IBM
zEnterprise EC12 (zEC12) or later mainframe.
User response
If your mainframe is earlier than zEC12, set the mode= module or
prng.mode= kernel parameter to 0 or 1 to run the
pseudo-random number device driver in triple DES mode.
Otherwise, ensure that MSA 5 support available.
