I found again that em28xx driver is crashing. I suspect it is bug in
DRX-K firmware downloading. It crashed two times. When it did not crash,
there was very often I2C communication failure towards tda18271 tuner
that is behind of drx-k. That makes PCTV 520e device unusable. It seems
to work fine when I comment out firmware and the chip internal firmware
is used.
I am not sure if it is really DRX-K issue as em28xx has also quite long
history of this kind of bugs. It is still suspect number one as I see
some drx-k fw routine names printed to crash dump.
Here is two different oops pictures:
