Re: pctv452e oops without HTML

since kernel 4.9 I cannot use my four dvb-s2 USB receivers anymore, so I am stuck with 4.8.x Now I tried again with an unmodified kernel 4.13.12. After some time, I get 3 oopses (remember - I have 4 devices). The call trace is always the same. attached: tasks.txt showing the timing of the
