find the appropriate -xx string to put in your .bat file. I forgot what it was. I suggest everyone turn off their log files unless you have problems.
Anybody reads what's written in the question?
First, it is Linux, there's no .bat file.
Second, it's not a miner log, it's system log, Linux kernel messages.
I think only Claymore can give any answers. But it might be the result of using amdgpu-pro drivers and newest cards. AMD drivers are not the best written software as was mentioned few times.
