Random freeze and error in logs

I have a cleanly installed the latest version and have occasional batches of errors in the logs.

Machine boots
A day goes by
10 sets of message like this:-

Does this indicate a failing SD card?

It could be a SD card on its way out. It can’t hurt to try another one.
