--- Comment #26 from Dorota Czaplejewicz <dorota.czaplejewicz at collabora.co.uk> ---
I managed to get more info about the issue I'm seeing. The symptoms have been
mostly consistent with my previous post.

The failure to sleep does not happen every time; I had to reboot up to 5 times
for the first failure to happen. Because of that, I'm not 100% certain if
"good" commits are really bug-free - I tested at most 5 reboots. "Bad" commits
are definitely correct though.

Suspend failure is somewhat correlated to failures in dmesg, like:
