I have marked two more downstream bug reports as duplicates of this one:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/533139
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/535454

In these bugs there were some slight differences:
- In the first one the CPU has started writing to the ringbuffer, but the GPU hasn't started writing yet (ACTHD: 0x00000000).
- In the second bug report the GPU has also started reading, and it has PGTBL_ER: 0x00000001 instead of PGTBL_ER: 0x00000001.
