[regression] 6.8.1: fails to hibernate with pm_runtime_force_suspend+0x0/0x120 returns -16

[Martin Steigerwald]

Hi!

ThinkPad T14 AMD Gen 1 fails to hibernate with self-compiled 6.8.1.
Hibernation works correctly with self-compiled 6.7.9.

Trying to use "no_console_suspend" to debug next. Will not do bisect
between major kernel releases on a production machine.
