One thing you can try is SNA, which packs its batches differently with the advantage that more auxiliary state is included in the error-state. It also packs all the kernels into a single buffer which will reduce the frequency at which it is paged out/in. So if you can reproduce with SNA (use Option "AccelMethod" "SNA" in a device section of your xorg.conf snippet) I expect the error-state to be quite different and hopefully shed some more light on the issue.
I tried this with latest 3.7-rc8 git, but no matter how hard I try, I can't get the gpu to hang (with i915.915_enable_rc6=0). Will use this as my default kernel the next few days and see if the hang occurs by chance.
Can you confirm one thing: are you able to reproduce the hangs at all on 3.7-rc8, using your original setup? -Chris
