Hi,
I've had this issue already with 8.0.1k, but I though an update might solve it. Unfortunately it doesn't, thus this report. I have a Mystique Satix S2 Sky/DVBSky S960 USB DVB-S/S2 tuner, that I'd like to use with LibreELEC on my MXQ Pro 4K box. Problem is, that while booting the device detection at some point throws an "Internal Error", see the logs here:

I can also provide kodi logs, but I don't think they are of much use, since the problem happens already before Kodi is even started.
I compared the firmware files in /lib/firmware with the latest ones taken from this page, but the files are the same (according to an md5 comparison) except for dvb-demod-si2168-a20-01.fw, but I don't know if this is relevant. Unfortunately, I cannot replace the existing one, since the firmware directory is mounted read-only.
Anybody has some hints?
