Kubuntu 18.04.01 - Ryzen 2400G / AMDGPU - Random system freezes

[Cannot Remember]

I am experiencing some stray lockups which are most likely related to AMDGPU. There is no apparent logic in the pattern with wich the system hangs and I cannot provide any steps to reproduce the problem. One time it happened as I clicked a link in Firefox, new tab opened and the system froze. Another time, Firefox was not open and I was about to edit a text file by clicking "F4 Edit" in Krusader and the system froze. When the system freezes, it is completely unresponsive and there are no other options than to reset and reboot. The system generates no error reports as far as I can figure out and the only apparent info are some entries in the syslog. I have appended relevant info below, if further info may be needed please ask :)

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1804505

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Cannot Remember (dinkidonk)]

I can add to this that I had lots of video lockups with 4.19.1, a day without was a wonder! Then I upgraded to 4.19.5 which did not help either. During one lockup I noticed that sound from a video was continuing to play for a while, so I tried to stick a flash drive into a USB port, and the drive was actually registered both being plugged in and removed again (syslog entries). Since the kernel seemed to continue to operate even when video was frozen, I thought this may be a MESA issue so I upgraded MESA using the Ubuntu-X Team PPA. That did not help either, so I upgraded to kernel 4.19.9 and this was a HUGE improvement in stability, no lockups for almost 2 weeks! But eventually it locked up, still with the same error being logged. Now I am on kernel 4.20, and there has been no problems for almost a week, but only time will tell... :)

[Cannot Remember (dinkidonk)]

Just had a lockup with kernel 4.20 :(
