Comment 12 for bug 1768627

OK can you both please do the following:

0) Observe where the end of your current dmesg output is
1) Manually turn on force power
# echo 1 | sudo tee
/sys/bus/wmi/devices/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power

2) Check in /sys/bus/thunderbolt/devices/0-0/ and read the NVM version sysfs node
3) Turn off force power
# echo 0 | sudo tee
/sys/bus/wmi/devices/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power
4) Collect all messages after the end of dmesg output notated in 0 (Not just thunderbolt ones)
