So first question of all is that board SBSA certified? Yeah, I can imagine. I can't find any info about SBSA cartification for that board hence I'd say= that state is unknown, hence most likely "no". At least that's what I think. It is a good question for cix or cixtech.com-based emails. They have some updated potentially unstable UEFI firmwares to test though. > If not then the chances of that board actually working correctly are very= low unfortunately. > >> [drm] amdgpu: 7886M of GTT memory ready. >> [drm] GART: num cpu pages 131072, num gpu pages 131072 >> SError Interrupt on CPU11, code 0x00000000be000011 -- SError > > Any idea what that error code means? Well, current thinking process that it means: -- bits 31:26 system error interrupt; -- bit 25 indicates that it was 32-bit instruction; -- 0x11 in lsb is probably implementation-defined which can be anything like bus errors, parity, access violations, etc That's probably not very helping here.
