same ACPI bugs here on Ryzen 5 1600 bought in the first week of May17 Asus Prime X370-Pro BIOS 4011 and Fedora 28 Workstation Kernel 4.16.8-300.fc28.x86_64:
I do not have enough knowledge to answer your questions technically, if they are not a problem for your purposes you can lose importance.
Linux users are still waiting improvements on AMD AGESA and BIOS updates from motherboards manufacturers before confirming that choosing the first gen of Ryzen has been a bad decision for us, or at least for me ... we will see what happens
Thanks for your response. After I saw the bugs I googled it and I saw dozens of people mentioning the same thing. What I don't like is that I sent back a CPU that didn't have that bug but was idle freezing all the time and crashing out of the blue and I received a new one with different issues.
I do hope that this is a software issue though that will be fixed with a BIOS or Kernel update and it isn't something serious. I also hope that someone can provide more details for us regarding this issue and explain what this bug is and what are its consequences,
I can't stop but wonder whether the fact that I received a CPU produced earlier (33th week) than the one I sent back (38th week) had something to do with that. I don't know whether the one I sent was somehow updated and didn't have that bug. Also I don't know whether the updated BIOS could produce that bug meaning that it doesn't have to do with the production date. If that is the case then that bug would appear in my returned CPU too. I can't seem to find answers about that.
Let's hope there is an update because running Linux on Ryzen has proven to be very challenging.
