Everything gets updated all the time since this is
a rolling distribution. However, I encountered the
problem already a few weeks ago but had to put it aside since
I had work to do. Downgrading the BIOS had resolved the problem.
I've been using a 7.2.6 kernel with the old BIOS for daily
work without problems. Prior to this BIOS update now I upgraded
the kernel to 7.2.8 and confirmed it can boot with the old BIOS.

FWIW, other Asrock boards got AGESA ComboAM5 1.3.0.1b Patch A
recently, but the mini-PC product line seem to be always
notoriously late in getting BIOS updates.
