Firstly, apologies for starting a new topic on this subject. I can’t make any more posts on the other E585 thread and I really need this computer to be stable. I do not wish to be a nuisance.
I’m still experiencing the hard locks I described in the other thread. Sometimes nothing is reported in the log file but usually I have errors like this:

I am running the latest KDE Neon, kernel 4.19.5. I have tried the padoka stable, unstable, and oibaf repositories for the MESA drivers but none of them fix the problem. Also have tried earlier kernels. Are other people experiencing this issue with Linux on the E585?
I’ve found similar reports on the Internet with regards to hard locks with Vega, but have not found any definitive causes or solutions.
I’m guessing that the hardware just isn’t fully supported? Will it be in the future? Any hints on what could be the problem or other things I could try would be greatly appreciated. Many thanks.
