Very new to RPi, LibreELEC, TVheadend and Hauppauge 950q USB tuner....but pretty familiar with run of the mill Linux/Unix.
The USB tuner seems very standard and works fine on Windows 10. On the above set up it works .... for a while? I can get to TVheadend via a browser, can log in to LibreELEC via SSH putty. TVheadend on RPi serves up video to various machines on the LAN via VLC. But....
After a while (sometimes hours) the video stream stops and the RPi seems to "lock up"
* I am running the RPi headless (no kb, mouse, HDMI....just hardwire to LAN, and the TV tuner)
* No response from the browser to TVheadend software after lock up
* No ability to log in to LibreELEC via SSH Putty after lock up
* Have to power cycle the RPi to get things back to working.
I see much discussion around firmware drivers for tuners. Pretty sure there are two possible here in the LibreElec standard distribution:
dvb-fe-xc5000-1.6.114.fw <== this one seem to get loaded at present
dvb-fe-xc5000c-4.1.30.7.fw <==not sure if my Hauppauge 950q USB tuner can/should be running this one?
For "starter" diagnostics I booted the RPi without the tuner. Then installed it. Then ran dmesg and captured the tail of that below.
Is there a troubleshooting procedure I can follow to pin down why the lockup? I'm not even dead certain it's the TV Tuner locking up the whole RPi, but it seems like the area of greatest probability?
