I applied
http://lists.freedesktop.org/archives/dri-devel/2015-January/074969.html on top
of kernel 3.18.4, and got:

radeon 0000:01:00.0: GPU fault detected: 146 0x0008080c
radeon 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x00000000
radeon 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0800800C
VM fault (0x0c, vmid 4) at page 0, read from 'TC0' (0x54433000) (8)

(following by an unsuccessful attempt to unwedge the GPU, but I guess the lines
above are what's really interesting).

This is with Mesa built from 8d2542fc9d5af4db355b67cc2a1ff2f413685a27 on a
bonaire xtx.
