Hi.
Have a ASUS - ROG crosshair viii hero, with an Ryzen 5950x.
When booting Linux kernel 5.4.80 on a Gentoo system it shows the following issue.
This is also been reported at redhat - https://bugzilla.redhat.com/show_bug.cgi?id=1551605#c53
Notice it seems to happen after AGESA update of the BIOS.
Have reported it to ASUS also, but would like to know if you have any details about it.
