Hello, I think I'm experiencing the same problem here. My Ryzen 5 2400G system
freezes often, especially under some high cpu and disk activity, even after the
"Typical Current Idle" UEFI workaround. Sometimes I could reboot with sysrq,
most of the times I need a hard reset. The freezes never leave a message in
kernel log until today, after 2 months I built my machine.

The HDD led still flashes after this freeze, but in the previous freezes, it
won't flash at all.

using kernel 4.17.0-041700-generic on Ubuntu 18.04, mesa 18.1.1-0~b~padoka0.
CPU runs at stock 3.6GHz, memory 16G DDR4, running at 2133MHz, no overclocking.
