kernel panic messages

This was with 4.19.0-rc4 on Fedora 29. Graphics card RX 570. This is new, did
not use to be a problem before. Isn't a problem with 4.18.5. /var/log/messages
did have a backtrace which is attached. A small interesting detail from the log
was that the machine appeared to function normally until 2 minutes before
reboot which is what makes me sure it was turning the monitors on that made the
kernel panic.
