None of that was supposed to be executing *except* during
(a) initial boot, when (b) the command line parameter was
set to enable that test during boot ... see test_suspend().

If we can't enter standby/suspend/hibernate then, it's
either a regression or a bug to fix; ergo the warning.

Clearly that's been changed at some point, and this problem
relates to those changes.
