Bug#900087: xserver-xorg-video-amdgpu: AMD RX 550 often locks up
I avoided trying early kernel-4.17.x versions, but yesterday I updated
from kernel-4.16.x to kernel 4.17.17-1, but frankly that change has
not helped this lockup problem at all. For example, after trying
direct use (with a KDE desktop if that makes any difference) for the
first time with that kernel, the kernel only lasted a half an hour
before I got a lockup which could only be solved by hitting the reset
button! And roughly 8 hours later after that reset I got another
lockup which also required a reset to regain control.
So it appears the substantial number of AMD graphics fixes in
kernel-4.17.x are not sufficient to stabilize use of this AMD RX 550
graphics card that should no longer be considered cutting-edge hardware
(i.e. it was first offered for sale at least 16 months ago).
Because of these on-going issues with direct use of this card, I am
going back to using the X-terminal method with this kernel which
experience with kernel-4.16.x shows is much more stable since it
avoids using this graphics card completely (except for the direct
display of the Linux console login prompt).
I will try again to use this card directly when kernel-4.18.x is
promoted to Buster.
