Could you please make sure you boot with drm.debug=0xe and also with log_buf_len=4M Also I'd like you to try another attempt. move /lib/firmware/i915/skl_dmc_ver1_26.bin out of /lib/firmware/i915 and regenerate your initrd. I'd like to make sure that firmware presence and loading is really impacting this somehow. Please attach dmesg for both cases. With firmware loading and without firmware loading. Because with DC states disabled firmware is not suppose to do anything anyways and the issue persist with dc_enable=0... Also runtime PM is probably not the culprit because the count is high.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
