Public bug reported:
since upgrade to ubuntu 20.10 my thinkpad x1 carbon gen5 resumes from
suspend with a roaring fan. i have to make sure to start the resume
while the power cord is not connected, let it wake up fully and only
then connect the power cord. this is quite an annoying regression, still
persisting in ubuntu 21.04, since there is no way to calm the fan noise
except to do a complete shutdown and power on cycle (reboot still keeps
the fan at max).
