Someone has posted a patch that fixes this issue on the intel-gfx mailing list and it should hopefully be in 3.0-rc4. afterwards we will be able to cherry-pick it into stable. I have test kernels available here that fix the issue, with the side effect of also massively speeding up 3D with the default i915.semaphores=0 from my tests, please do post your results if you test it.
