I can reproduce with following steps:
1. do factory recovery (Xenial oem install)
2. upgrade linux-firmware along to 1.157.22
3. completely power off and reboot after 1 minute
4. trigger system suspend
In the beginning CAP lock indicator is blinking, and then keyboard may
have one flash, then power LID always on and leaves the system hard
lockup state. No response to kernel magic keys or power button (short)
presses.
