Boot log errors are they a problem?

Below are listed what the system called fatal errors. Better minds than mine, I hope, can tell me if there is any thing of concern.

In general yes they are a problem. Specifically, are you having problems? What you should do is copy the message and paste into your favorite search engine and see what they mean and if they can be fixed and how.

@fbt89 thanks I did run sysbench [outputs below] and use the machine, up time 24 hours.
After boot all applications appear to be running fine.
I am replacing window$ for a family member who does not want to spend any money on the laptop.
If I have missed some thing please let me know.
