Have you updated libdrm recently as well?
I last updated libdrm from git on the 14th, I'll update it and see if that helps.
https://cgit.freedesktop.org/mesa/drm/commit/?id=33a2851ab9bc3cd8a68bedf4cf0fdc549b0f3596 should fix this.
Yeah that commit came to my mind as well.
Thanks for your patience guys. Using kernel 4.16-rc2 (but with the bisected commit reverted) X and weston work. Updating libdrm to master-33a2851, X and weston work again (yay!). Updating also mesa (master-af5f232), now I'm getting hard lockups. Downgrading the kernel to 4.15-rc9 or using the 4.16-rc2 kernel with 5b565e0 reverted and things work again. Maybe a new related bug, but in mesa?
