I regularly get these erros below. Can anyone tell me if I need to be concerned with these erros?
You do not. Normal hardware chatter.
How did you even get any logs? mine are blank ever since installing ASL3
You are looking at /var/log/asterisk/messages.log ?
Don’t get too caught up in “errors” in Cockpit. There are a lot of system services running that may have “errors” from time to time that you don’t care about.
I’d suggest stop looking at kernel/dmesg errors 
It’s really not something to look at unless you’re having an actual problem.
