dmesg log

I'm using Arch Linux with Linux 4.20.6, X11 and the modesetting driver toge=
ther
with the KDE plasma desktop (5.14.5). After using the desktop for a while (=
in
particular, after causing some graphics load) visual artifacts appear and
plasma-desktop often hangs up. Sometimes the hanging process can be restart=
ed,
other times X is completely frozen (but can still be ssh'ed into).

The dmesg log shows these lines, although only the fifo DMA_PUSHER lines se=
em
to consistently appear every time the problem is triggered:
