Created attachment 117962 --> https://bugs.freedesktop.org/attachment.cgi?id=117962&action=edit dmesg of hang
I've been getting random hangs in amdgpu_ring_lock, this causes X to hang, meaning I can't use the computer at all. I can sometimes switch to a tty, but this doesn't always work either.
I'm running Ubuntu 15.04 with mesa and libdrm from the oibaf ppa, with a self-compiled xf86-video-amdgpu and a self-compiled kernel from agd5f, drm-next-4.3-wip (9066b0c318589f47b754a3def4fe8ec4688dc21a).
I haven't been able to predict when the hang will happen, sometimes I can use it for several hours before it hangs, other times it happens just a few minutes after booting.
