On some AMD Ryzen X570 (Gigabyte) motherboards, virtualization is disabled in the UEFI firmware (BIOS). If are having trouble running qemu or virtualbox, the kvm module is loaded, and lscpu indicates that the CPU supports KVM, go into the BIOS, Tweaker menu tab (advanced mode), find "Advanced CPU settings" and enable "SVM mode".
On some boards, you can find the KVM settings under "Advanced CPU Core Settings" option group, under M.I.T tab - "Advanced Frequency Settings" option group - frequency settings - CPU core settings.

One of my Slackware systems has two optical drives: Blu-Ray and DVD: /dev/sr0 and /dev/sr1. In 14.2 as well as current, if neither are used for awhile, some of the udev symlinks to /dev/sr0 disappear. This becomes maddening (as in WTF?) when I'm trying to run my qemu VMs and I get the error:

I have finally had some time to compile the benchmarks for a series of GPUs on the new mini-ITX build. The purpose was to see if the amdgpu driver is ready to compete with Nvidia on a Linux powered game box. The GPUs choices are simply what I had available and fairly recent, except for the RX 5700 XT, which was a new purchase.

In the "what could go wrong category" for information found on the interwebs, there is a work around for the missing support for the 0x8688 sensor in the new Gigabyte GIGABYTE X570 I AORUS PRO motherboard. [EDIT: This seems to be applicable to any GIGABYTE AURUS X570 motherboard to at least kernel 5.4.x]
Out of the box, CPU temperatures/voltages are available (k10temp), as are GPU temperatures/fan and voltages (amdgpu). Motherboord and CPU fans however are missing. To the kernel boot parameters in '/boot/efi/EFI/Slackware/elilo.conf' add 'acpi_enforce_resources=lax':
