I found the performance test stopped at at least 2 cases: glb3016_gl_driver and OglBatch5_6.

The attachment indicates you are hitting bug #90410, which is unrelated to the system hangs.

If you run those tests separately, do they cause the system to hang?

So far, I didn't find any cases cause system hang when run them separately, but I'm not sure whether this issue could be  reproduced by this way. The tests stopped at different cases everyday, but the error were the same.

Do you see any other error besides "*ERROR* mismatch in ddi_pll_sel"?

I didn't notice that, I will give you a feed back next time we meet this issue, and attach demsg as much as I can.

The same error (https://bugs.freedesktop.org/show_bug.cgi?id=90410) has been fixed against drm-intel-nightly branch, and this bug reported system hang with the error problem did not appear also, so close as verified.
