Well another watchdog failure with 4.14.5
I also updated to AGESA 1.0.0.6B when I rebooted to 4.14.5.
Just building a 4.14.6 to try again.

@franckc did you have to rebuild your kernel? I tried the kernel
options without that and still had failures. I've just rebuilt with
CONFIG_RCU_NOCB_CPU to see if now the rcu_nocbs=0-15 resolves my lockups

Cool Thanks for the confirmation Franck I've rebuilt 4.13.0-17 with
instructions from here https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
(Probably similarly to Mario). I'm going to test it with this first
(since don't really want to reboot again). But might get stuff ready
with a 4.14.3
Yep I did :) thanks

Well I've hit 48 hours uptime since booting to my custom build kernel
(Linux ganymede 4.13.0-17-generic #20+ryzen SMP Sun Dec 3 20:18:51 MST
2017 x86_64 x86_64 x86_64 GNU/Linux) with rcu_nocbs=0-15 in my boot
command and disabled ASLR. That's about double my previous uptime
record, I'll report
After 5 days uptime with my custom ubuntu kernel build I got a different
crash with a reboot vs the watchdog error. I'm now running a mainline
kernel 4.14.3 with ASLR disabled and rcu_nocbs=0-15 and have restarted
my no crash counter.

My corrent config to get stability
C6 disabled in BIOS
ALSR disabled
kernel >= 4.14.4 with CONFIG_RCU_NOCB_CPU
rcu_nocbs=0-15 processor.max_cstate=1 in GRUB_CMDLINE_LINUX
I got lockups still with ASLR disabled and rcu_nocbs with the custom
built kernel, once I added C6 disabled in bios
Well I've now hit 3 weeks of uptime with C6 disabled in the BIOS and
GRUB_CMDLINE_LINUX_DEFAULT="rcu_nocbs=0-15 processor.max_cstate=1"
and 4.14.6 built from the mainline kernel repo. At this point I'm
satisfied that for me at least my Ryzen is now stable.

Just to be clear my mainline kernel is configured with
CONFIG_RCU_NOCB_CPU to yes.

I can confirm this problem on Ubuntu 18.04 with kernel 5.0.0-23-generic.
I'm on a Lenovo Thinkpad with r8822be wifi adapter.
