Comment 51 for bug 1328727

Wow! Here I am to revive this topic in 2019! I have exactly the same problem, on ubuntu 18.04.2 with basically all kernels since 4.15.0-42 up to 5, which was all I tested, currently on 4.18.0-17-generic... I guess this has nothing to do with the kernel anyway.

It was working fine before, even with proprietary nvidia drivers which would generally cause a bug on the resume and not while saving the ram snapshot. I've been trying to tell this to the ubuntu guys and you can see my whole story with this problem right here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1819915

Shortly, I tried with or without nvidia modules enabled (or intel or using nouveau), many different kernels, disabled i915, and this is all get in all those different combinations: https://launchpadlibrarian.net/417327528/i915.jpg

The event is pretty random and seems to be more likely to happen after 2 or 4 gb of ram is ever used (I have 16 in total), and nothing changes if later I reduce the ram usage later. But is random, I successfully hibernated with 11gb in use yesterday, just resumed and hibernated 5 seconds later without doing nothing else than running hibernate, and got freeze there.

This also happens randomly if there's just 3 or 2 gb in use, likely on the second attempt of after more than 5 minutes after the computer is on. What can be wrong here?
