Description Matthias Schojohann 2015-07-10 13:23:16 UTC 
iBook G4 1,41GHz and every once in a while i get an error on the terminal that says:
WARNING: Current temperature (CPU BOTTOMSIDE: 255.0 C) exceeds critical temperature (80.0 C); count = 1

sysctl dev.adt746x.0.sensors.cpu_bottomside.temp however gives me temps like 50.0 C

Justin Hibbits via the ppc ML:
"255 is (char)-1 on PowerPC, so it indicates an error reading from the
device.  I'll take a look at it, and try to silence the error"
