<br>
/lib/firmware/'current kernel' Probably dated back to 12.04 or 16.04 . I used to have to copy NXP7164_2010-03-10.1.fw to /lib/firmware/'current kernel' after kernel updates , or I would get intermittent pixellation in recordings.<br>
After 20.04 I no longer need to do that. That's probably when /lib/firmware/'current kernel' ceased to exist.<br>
<br>
The output of dmesg | grep "\.fw" :<br>
<br>
[ 6.047781] saa7164_downloadfirmware() Waiting for firmware upload (NXP7164-2010-03-10.1.fw)<br>
[ 22.767075] tda10048_firmware_upload: waiting for firmware upload (dvb-fe-tda10048-1.0.fw)...<br>
[ 28.488814] tda10048_firmware_upload: waiting for firmware upload (dvb-fe-tda10048-1.0.fw)...<br>
<br>
My system boots for recordings and then shuts down<br>
<br>
I compressed the four firmware files to see if it makes any difference.<br>
