Currently running Ubuntu 19.04. I am attempting to follow the steps here to trace the problem: <a href="https://wiki.ubuntu.com/DebuggingKernelSuspend">https://wiki.ubuntu.com/DebuggingKernelSuspend</a> This is what I have done so far: $ sudo apt install pm-utils $ sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" I resumed but got my usual screen garbage (looks like static on the screen). I ssh'd in and did a sudo reboot Right away I ran this: $ dmesg > dmesg_post_boot.txt I looked for Magic number in the dmesg per the ubuntu wiki above and found these lines: [ 0.950964] Magic number: 0:66:1001 [ 0.950965] hash matches drivers/base/power/main.c:1012 Now the instructions are to exclude this module from the next boot and see if I can replicate the problem. How do I exclude main.c or do I even want to? Is it even possible that the bug is here?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
