It's also possible that there is a bug and it just crashes :)
Also, I do suspend devices before the page copy, and I quickly hacked a
PMU sysdev that should suspend ADB interrupts (at least) so that should
be fine, except if you have a brightness request in flight maybe ?
The whole PMU suspend thing must be reworked I suppose. (And the battery
monitoring thing "paused" as well, we must wait for async PMU requests,
that is at least battery requests and backlight ones to stop)
