Commen= t # 9 on bug 11011= 7 from Craig 
I would like to add to this some additional troubleshooting I =
have performed,
in case it is of use.



just a short history: I am unable to suspend with any Linux distribution an=
d be
able to resume again. Currently running Ubuntu 19.04.

I am attempting to follow the steps here to trace the problem:
https://wiki.ubu=
ntu.com/DebuggingKernelSuspend

This is what I have done so far:

$ sudo apt install pm-utils
$ sudo sh -c "sync && echo 1 > /sys/power/pm_trace &&am=
p; 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?
