mid and high profiles seem fine.

vger 0000:02:00.0 # echo low > power_profile
vger 0000:02:00.0 # cat power_profile
low
vger 0000:02:00.0 # #sluggish desktop
vger 0000:02:00.0 # echo mid > power_profile
vger 0000:02:00.0 # cat power_profile
mid
vger 0000:02:00.0 # #all good
vger 0000:02:00.0 # echo high > power_profile
vger 0000:02:00.0 # cat power_profile
high
vger 0000:02:00.0 # #all good
vger 0000:02:00.0 #

and they make a difference at the power socket for the whole system, so they
are doing something:

low   ~128W
mid   ~168W
high  ~182W

ok this may be unrelated but it's writing this message every profile change.
