Comment 2 Ilia Mirkin 2017-08-10 00:46:04 UTC
The issue at hand being the multiple

WARNING: CPU: 0 PID: 1 at drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c:180 .nvkm_outp_init+0x170/0x2d0

which happen inside nvkm_disp_init. According to Alex, the board works fine (except for MSI being broken, but that's unrelated).
Comment 4 Ben Crocker 2018-01-30 21:47:22 UTC
I note that, according to the dmesg output, this is PPC64 big-endian.
Can you provide other hardware specifics?

I see that Ben Skeggs' commit is in the kernel repo as
commit 372aa73e20197d463fc8b34524c20b089a98b1c3;
is anyone equipped to test the fix?

Can we close this as RESOLVED/FIXED?
