Could you clarify your report that the board can't be booted? Are there only two scenarios: 1. The board boots with the error messages 2. The board boots without the error messages Or is there another scenario which you refer to as "can't be booted"? In the case where booting without the error messages, is there some other issue you see (system stall reported on <a class="bz_bug_link bz_status_NEW " title="NEW - System stall on Supermicro SKL boards on drm-tip" href="show_bug.cgi?id=105949">bug 105949</a>)? Did you try to bisect the problem causing the above error messages (noting that you need several boots for each bisect step)? Specifically there's been a recent related WA, could you try if the problem persists reverting that on top of drm-tip? I attached the revert patch since it won't revert cleanly.
