Yeah, for small amounts of time, I do expect that the suspend time will be slightly shorter than the time that applications are frozen - obviously to your point about the suprious irq case, that delta might grow with suspend time, but I'm hoping we're still dealing with relatively small amounts that won't confuse applications. But from the bug report it sounds like timekeeping is just never getting suspended at all, which is unexpected.
Default seems to be WatchdogSec=180 So that's not a small amount of time.The problem only happens at about 1 in 10 times when resuming from s2idle. And s2idle is the only supported standby mode for this hardware.
