First boot after flashing results in power off

[crawfxrd]

After successfully flashing from proprietary firmware to firmware-open, the machine powers off.

Expected behavior

The machine turns on, powers off for ~2 seconds, and then turns back on.

Actual behavior

The machine turns on, powers off, and remains off.

For what it's worth, we've considered this expected behavior and added a note to the support article that powering on more than once may be necessary after flashing is complete. There's also a PR open to add similar messaging in the Firmware Manager app. If/when this gets fixed, we may want to remove the corresponding notes from the documentation and GUI.

Cause may not be the same, but this is going to become very apparent after the coreboot update. coreboot will issue a global reset after changing the IME mode to put it in the correct state.
