If it's the same issue, it's fixed with these patches: https://cgit.freedesktop.org/drm/drm-misc/commit/?h=drm-misc- fixes&id=e0658f970a7f3d85431c6803b7d5169444fb11b0 https://cgit.freedesktop.org/drm/drm-misc/commit/?h=drm-misc- fixes&id=a73858ef4d5e1d425e171f0f6a52864176a6a979
OK, thanks. I've sometimes used the whole graphics stack built from source; I'll do it again, using the latest drm, and see if that fixes it.
