At the end of that report, "[PATCH] drm/i915: Undo gtt scratch pte unmapping again" is mentioned. Shall I revert that patch, is that your suggestion? Lenovo T440s BIOS version is GJET60WW (2.10). 3.13.11 does not produce these corruptions, it only hangs sometimes when starting hibernation at freeing memory, could be some freezing problem, but I believe it is still driver related. The real issues start with 3.14 (as explained in <a class="bz_bug_link bz_status_REOPENED " title="REOPENED --- - [ivb] GPU hang after hibernation, IPEHR: 0xf000027e" href="show_bug.cgi?id=80727">bug #80727</a>), and the corruptions appear only in 3.15.2 AFAICT so far. I believe I've not seen these corruptions with S3, but that may be another thing to thoroughly investigate...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
