Only the latest version is supported. Can you update the kernel/system and see if the problem persists? |
 |
Thanks！ You mean the latest version is the latest CentOS 8.xxx or the latest kernel version 5.xxx ? |
|
|
I mean the latest CentOS 8.xxx kernel. |

Hi，toracat, I use the latest CentOS-8.2.2004-x86_64(kernel:4.18.0-193.el8.x86_64) , however, there is the same question , Can you help confirm the problem why it happens? Thanks! |
