3.18.1 + 3.18.3-3: W1 (DS18B20) - no valid data returned

[crashmaster]

Hello to all,

i switched back to 3.18.0-1 because my 1wire temperature sensor didn't work anymore with the latest kernels, it always returned 85 degrees (which normally indicates a reset of the sensor).

Anybody having the same problem?

Have you uncommented all the required DT overlays in config.txt?

Hi moonman,
not all, i uncommented only the two lines for W1.
The w1 modules were loaded and the kernel shows the sensors address in /sys. Basically everything works fine without any error messages. w1_therm returns always 85 degrees (crc checked like any other result).
