One bug I reported in August 2017 with <a class="bz_bug_link bz_status_NEW " title="NEW - [DC] System crashes when woken up from S3 sleep while HDMI display is switched off" href="show_bug.cgi?id=102323">https://bugs.freedesktop.org/show_bug.cgi?id=102323</a> - that one was fixed quickly. The next S3 resume crash I reported in October 2017 in <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - [bisected] Systems hangs on resume from S3 sleep due to "Match actual state during S3 resume" commit" href="show_bug.cgi?id=103277">https://bugs.freedesktop.org/show_bug.cgi?id=103277</a>, that one stayed without any resolution until April 2018, and the fix found in that report only works if no "drm.edid_firmware=..." kernel command line option is used. Another crash bug with S3 resumes I reported for 4.17.2 kernels in <a class="bz_bug_link bz_status_NEW " title="NEW - "BUG: unable to handle kernel paging request at 0000000000002000" in amdgpu_vm_cpu_set_ptes at amdgpu_vm.c:921" href="show_bug.cgi?id=107065">https://bugs.freedesktop.org/show_bug.cgi?id=107065</a> - then realized that 4.18 pre-releases exhibit the very same kind of crash immediately upon starting X11. For this crash upon X11 startup, there is a patch in the bug report, but it does not prevent the S3 resume crash. I currently work around S3 resume crashes by switching to the console display before enterin S3 sleep - but this is really an awkward work-around.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
