I’m sorry @dvo but those logs don’t give me any new ideas - I would suggest again that you request the plugin’s developer do some debugging to help figure out what it could be.
Sure, and over ~3500 commits b/w the 5.4.59 kernel in 3.10 and 5.4.79 kernel in 3.14…
(the reason I bring this up is because I’m currently debugging a network issue on my pi4 with 5.4.79 and particular switch setups that wasn’t there on 5.4.59 kernel…)
Either way it would be good to isolate first if the source of this problem that shows up only while using this plugin. Or do you face this high cpu+delay issue with other sources as well?
