These errors come during ubuntu boot up, not sure what they mean.
I thought these were due to BIOS but I did my BIOS update after these started coming and they still remain (BIOS update was done from windows, I have a dual boot system).
On the second error screen it takes some time but ubuntu eventually does load after it.
Right now in my laptop I am also encountering another issue wherein it freezes randomly, is it related to that issue?
