Involuntary reboot log 12.4

Screen went black and machine was unresponsive to key presses, power button, opening/closing, plugging/unplugging (tried Thunderbolt dock and also Apple-provided USB-C charger). After a couple hours of fiddling, eventually a long power button press (greater than 10 seconds) forced it alive again.

Even so, after this event machine is still one of the most reliable I’ve had to date, with an average time between failures of 142 days (only the Liferay machine was better, as it never had an involuntary reboot in its entire 844-day history).
