Can you please check if this still happens with the newest iterations of the kernel, both please 7.1.13-1 in unstable and 7.2.3-1~exp1 in experimental (since we will move 7.2.y soon to unstable). If you still can reproduce the boot error with two cards in, can you please report the issue to https://gitlab.freedesktop.org/drm/amd/-/issues and then report back to us the upstream issue reference so we get aware when the issue is addressed (and mark it forwarded accordingly)? Regards, Salvatore
