I am running raspberry pi 3 with desktop dashboard.
I accidentally upgrade the kernel to 4.9 and then downgrade it ot 4.4.50
I am not sure if it is due to update, but the dashboard becomes completely laggy and unresponsible. Also relay board are getting very long to connect:
If I close the tab with the dashboard, the browser goes fast and there is no problem.
Also I have noticed a problem with MQTT devices. They can not connect. If I restart, sometimes they connect and sometimes not. Also they are listed as OFFLINE, but last packet data send is just a seconds ago and widgets values are changing.
I have also note that when try to open the Raspberry pi device in Android app, nothing is showed. Arduino is working fine.
Also trigger a relay is taking too long (the widget is rotating).
Note also how many DS18B20 are added automatically to the dashboard:
What is the stable Kernel that we have to use?, because I am pretty sure that is from the update and downgrade that I have made.
