Summary0018285: Kernel mce module panic during boot with AMD B550 chipset + Ryzen 7 5700G CPU
DescriptionWe tried to install CentOS 7.9 2009, and always got a kernel panic during boot.
The hardware is a Ryzen 7 5700 G CPU with a motherboard of ASUS TUF GAMING B550M-E.The chipset is AMD B550.

After some analysis, we tried to add the kernel boot parameter "mce=off", and the kernel booted successfully.

For CentOS 8.4 2105, there is no problem.

The only way to have this problem fixed for good is to open a bug at and pray that RH fixes it.
Unfortunately RHEL 7 is already in maintenance state and only important - mostly security related - bugs get accepted. So, especially as there already is a workaround for your problem, most probably the bug report will be rejected.
