I can offer some explanation, though...
The regulator quirk code masks all interrupts and events. Some of these events
are error states, but not all of them are. Hence they may be set (and cause
problems due to unhandled interrupts without the quirk) depending on power
consumption on the various power rails. The latter are influenced by secondary
CPU booting, and possibly by configuration of reset debug hardware.
