Comment 472 for bug 1690085

Interestingly,

I had a nicely running system, uptime about 30 days, and I just decided to upgrade the Kernel to the latest (Fedora 28), and "what the heck" I will just upgrade the motherboard BIOS too.

Mobo: ASUSTeK model: PRIME B350M-A
6 core AMD Ryzen 5 1600X Six-Core (-MT-MCP-) arch: Zen rev.1

So, now I have BIOS version 4104 (previous was 3801 I think)

And after like 10 minutes of doing stuff (i.e. not idle), LOCKED UP !!!

So I went into the BIOS and changed the Global C-State to Disabled, and right under that is the power profile, changed it to Typical.

We shall see how long it lasts !

I guess "don't fix what ain't broken" applied to my activity today lol.
