Patch 28831618 for AIX dated May 6, 2022 8:40 PM (Friday) didn't work for me.
This overlay patch usually fixes the problem with each released v19 RU of:
2022-05-07T11:13:41.334234+10:00
Error attempting to elevate VKTM's priority: no further priority changes will be attempted for this process
VKTM started with pid=5, OS id=23200104
Starting background process GEN0
VKTM running at (100ms) precision
The <<EXPECTED>> (after patching) result is;
2022-04-28T09:55:18.405185+10:00
VKTM started with pid=5, OS id=66060588 at elevated (RT) priority
