Error description

• ABEND0C4 KO2XLKD2+330 (at PK72967 level) on a D5034004A1FA (CLC)
  instruction with 64-Bit GPR4 = 00000000_00000000.
  Also KO2XLKDA + x'36E' at pk72967 instruction
   d501 4000 A20A = CLC
  KO2ORCVB is called to handle the program check, but KO2ORCVB
  failed to realize the addressing mode and itself program checked
  with ABEND0C4-38 KO2ORCVB+1106 (at PK27397 level) on a 58F0F070
  (LOAD) instruction, 64-Bit GPR15 = 00000010_31BF7F68.  Since
  KO2ORCVB again will be driven due to the program check, a
  program check loop ensues.
  Two problems are addressed in this APAR.  First the original
  program in KO2XLKD2 not checking for a valid address and second,
  KO2ORCVB not setting the addressing mode to 31 bit before using
  R15 to address the $TCA in Extended User Region (under the BAR).

  repeats throughout all of system trace.
