Does the screen freeze completely (e.g. the clock doesn't change)? Magic SysRq doesn't work? Are you running Chromium by any chance?
I did some research and found the following kernel bug:
Fedora has CONFIG_RCU_NOCB_CPU=y in the 4.15.8 kernel configuration so I added "rcu_nocbs=0-7" to the boot parameters and it has been running stable for a while. I have also added "nopti" as well as there is some anecdotal evidence it improves stability but I'm not sure about that.
There is also some discussions in the bug page about old PSUs not providing good enough low voltage, AMD is recommending running a newer PSU (post-Haswell) but for the time being the boot config is working for me.
Greetings,
Jorge
