I see. But that is assuming that the 1.0.0.4 version “fixes” this issue. At 
this point it’s only a guess but it seems likely given the previous replies 
I’ve seen. 
My god what a nightmare this has been. :-)

Best,

Title:
  Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks

Status in Linux:
  Expired
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Here is kern.log entry when happening :

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  
  Thanks
