Comment 7 for bug 1903467

Hello,

I have the same problem with random freezes. My Ubuntu 20.04.2 LTS (kernel: 5.8.0-44-generic) enjoys crashing randomly without any apparent reason.

I have 8 GB of RAM and started with 2 GB of swap when I installed it parallel to my Win 10 (dual boot, they share a harddrive). Recently, I added another hard drive, and today, I have managed to upgrade my swap to 21 GB in total (I "cut off" a part of my second hard drive (which is used as storage) and turned it into a swap partition with priority 1 that is automatically mounted at system start).

However, since I have my 21 GB of swap (it is working and shows up in the system monitor window and with swapon -show), the system froze twice: The first time when my machine was simply being idle (I had some firefox windows and an R session open but was AFK, I just realized that it was frozen when I came back) and the second time while I was starting to write another comment about this problem (nothing big was running, just a few firefox windows).

So I don't think that swap will solve this problem (at least it obviously didn't solve it for me). I've also got an AMD processor and the same problems, so maybe it is due to the processor?

I have always blamed the updates because there was often a note about new updates or a really long start-up time with the "Ubuntu-is-loading"-screen during the restart).
Since I suspected LivePatch to cause these freezes, I have already disabled LivePatch and check for updates manually on a regular basis. Just before the freeze, I had installed the current update (via the built-in software updater program), and it seemed as if everything was OK with the update.

Is there anything to log whatever happens when the system freezes? Because whenever the system freezes, all I can do is move the mouse, but clicking and the keyboard don't work. Sometimes I was lucky enough to be able to see the System monitor window, but that didn't indicate any problems (e.g., only 12% of CPU used and less than 1.6 GB of memory).

And, more importantly, is there any fix yet?
