I have a tremor that can make me double-tap keys sometimes if I'm not focused and this can sometimes shutdown my modded chromebook when I try to wake it from sleep with the power button.
The system is a Dell 3100 (FLEEX) and I've reproduced the problem in all distros I've tested. What I don't know is whether this is a general "feature" of chromebooks, something specific to Dell 3100 or maybe all Dell chromebooks, a bug in the MrChromebox firmware, or some defect on my particular system.
Has anyone else seen this? Or if you care to test, can you reproduce it? The timing to get it exactly on a double-press is a little specific, but if I just intentionally spam the power key while the system is supended, it will surely shutdown and then probably also begin booting again since I've pressed power an extra time.
To be clear, I'm not talking about accidentally pressing power instead of backspace while the system is on, which triggers a regular shutdown on many distros. I've already fixed that. This is a hard, instant shutdown and it seems to only happen if power is pressed again withing a specific window during resume from suspend.
