Summary0017980: kernel BUG at lib/swiotlb.c:453!
Description
I need your help.
Several server was rebooting. The below is system info and log.
I think it's similar to our issue and this link issue(https://bugs.centos.org/view.php?id=16057).

Could this be solved by upgrading the OS from 7.4 to 7.6?

Only the current version gets any support and that is 7.9

Can this problem be solved only by upgrading to CentOS 7.9? Is there any other way?
Happy New Year!
