Hello to everybody.
I’m running OSMC with Kodi 19.1 (VERSION_ID=“2021.08-1”) on a Raspberry 3B.
I’m having a bounch of “Division by zero in kernel” messages during the boot.
After that everything seems to function proprerly.
Can anybody help to understand those messages and what I have to do to remove them?
Here are a couple of them:
