Hi,

i got the extreme drain again and captured some logcats.

While experiencing the bug two thirds of the captured log (over 20min, airplane mode, as much disabled as possible) consisted of the following messages:

After a reboot that fixed the problem, the closest messages I could find were:

The bugged log also contained the following lines (as expected)

The other messages in the log did not repeat in such an aggressive fashion and seem normal, I still have the full logs here if you want me to look for something specific.
