SONY cxd2837er I guess?

see what is changing mostly in IRQ status

watch -d cat /proc/interrupts

First you should update to the latest version.

Thanks for your help
You are right, it's SONY CXD2837ER.
By using your watch -d cat /proc/interrupts,
122, 123, 124, 126, LOC, RES, CAL are changing mostly, but they are changing all the time, I can't tell if they are related to the Continuity counter error.
NMI, PMI, IWI seem to change when there's a Continuity counter error, but not always.

Thanks, I'm running the latest stable version, 4.2.8-36~g5bdcfd8ac

Updated by Flole Systems about 4 years ago

Issue reports for 4.2 are no longer accepted. That version is old and no longer maintained. Latest master contains many fixes, so it's a good idea to use it.

Short: you don't have the faintest idea and your are poking in the fog....

CXD2837ER had already problems with 4.3-1857~g221c29b40 and mchehab (!) looked
at the tvh and dvb kernel code ..... unfortunatly the issue hasn't gone away.

Try: "Force old status"
