Crashes on Fedora 26 with Ryzen 1700

[johnjohnjay]

I have the following build:
https://pcpartpicker.com/list/rcGGXP

I dual boot Fedora 26 and Windows 10.
On Windows I've never seen any slow downs or crashes, but on Fedora 26 I've been experiencing random crashes and reboots under normal load (basically web browsing and chatting).

In my last crash I got this error on journalctl:

watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [Chrome_SyncThre:3871]

As for uname:

$ uname -a
Linux localhost.localdomain 4.15.3-200.fc26.x86_64 #1 SMP Thu Feb 15 17:56:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

What could I do to track down the issue?

I've tried installing sensors to check the temperatures but it couldn't detect anything besides my graphic card.

Thanks in advance.

I doubt it is a temperature issue since you likely default to the motherboard fan profile.

There's also a lot of discussion around the microcode updates so you may have been pushed an update automatically through MS Updates that is now causing some issues with Ryzen.

Not sure if you need a new KERNEL or not.

I'm just not a Linux guy so you'll want a better opinion. I'm just Googling to see what others have said (and have had my own issues recently with Linux freezing).

One of my issues was VLC 3 which can lockup the system (now a know bug).

Use an older kernel. On startup you should have the choice of 3.
I run Fedora 27 with an older kernel from Fedora 26 and have no problems.
