    I've had very good luck with this board combined with this memory and my 2400g. I had some issues with the 4.16 kernels and a few GPU hangs while playing Batman Arkham City but all in all my Raven Ridge has been excellent. I'm running Mageia 7 (cauldron) kernel 5.0.6 and Mesa 19.0.1.

    I've read many a horror story about the issues people have had with their Raven Ridge systems, I guess I've been fortunate mine has been so well behaved.

    I hope Michael's rig behaves itself because the 2400g really is a fascinating processor.

    This sounds like an important thing to know. Which boards/OEMs have requested Linux support? Seems logical that we should be buying their hardware in this case.

    In general the showstopper problems on Linux are platform issues that are fixed in the sbios. There are fixes in the driver too, but they tend to be for smaller corner case issues.

    On the graphics side, we use a few commercial boards, but mostly AMD engineering boards and OEM platforms where Linux support was requested. This biggest issues generally come down to UEFI and ACPI. Most OEMs only validate windows and windows doesn't enable a bunch of features that Linux does. The most problematic ones are IOMMU and interrupt remapping (IVRS tables). The boards usually have the ACPI tables, but they tend to be buggy since windows doesn't use them. Getting a sbios that works properly with Linux is the best bet unfortunately.

    I think there's a bug in amdgpu because when I update to kernel 5.0.6 I got stuck on "fb: switching to amdgpudrmfb from VESA VGA" at boot, so I stayed on 4.18
