I was assuming we fixed these, but we might ended with a new one since
the TTY is changing a little bit and the Bluetooth TTYs are special
since they are pure virtual TTYs. Can you reproduce this crash every
time or is it happening only now and then?

During the last weeks, I am chasing an USB issue with the USB anchors
and how we use it. You might be hitting the one.

Regards

Marcel
