--- Comment #9 from Chris Wilson <chris at chris-wilson.co.uk> ---
Oh, that is interesting. The kernel did not release the fence for the vertex
buffer, which is naughty.

0x018000d8:      0x7d040031: 3DSTATE_LOAD_STATE_IMMEDIATE_1
0x018000dc:      0x01500000:    S0: vbo offset: 0x01500000
0x018000e0:      0x04040000:    S1: vertex width: 4, vertex pitch: 4

but

    01500000   262144 76 00 19dc 0 dirty render uncached (fence: 11)
  fence[11] = 01500031
    valid, x-tiled, pitch: 4096, start: 0x01500000, size: 1048576
