For my reference : MG

Machine hangs and reboots randomly.
Did a OS Restore still the same. It runs for 1-2 days and then won't turn on.

Touch Bar has no display. Touch is working.
Kernel Panic is in the lines of " Virtual I0Return"

Was checking UR300 - Board on Bench. JR900 disconnected.
All okay.
MGL_1v is 0V.
DMIC_DISABLE is 1.25V

PPBUS_AON was 12V.

LID Sensors work perfectly but if we keep the LID open. the screen will not go to sleep. (Settings are set to 2 minutes of inactivity. )
