VM64644 WAIT9050 CPOWNED PACKS IN TPF MODE
For any VM user with a CPOWNED pack in TPF mode
z/VM V5.R4 users with CPOWNED packs on TPF mode logical subsystems
go into a WAIT9050 at IPL after applying VM64449 which is on
Stacked Product RSU 5403RSU, CP Level 0901.
VM64644 was taken to address this problem, the APAR is expected
to be closed by mid May.
Configuring the CPOWNED packs to non-TPF mode logical subsystems
circumvents this issue.
