Created attachment 1432398 [details]
Output of journalctl -b | grep Hardware

+++ This bug was initially created as a clone of Bug #1469488 +++

Hardware Error
I have added an attachment with the complete output of journalctl -b | grep Hardware. As has been reported since Fedora 25, systems with the Intel J4205 and (in my case) the Intel J3455 processor come up with a Hardware Error early in boot. Is this a real error, or something to be ignored? In any event, it would be good to go away.

Notice that my microcode number is different from bug 1469488, but the PROCESSOR 0:506c9 is the same. I don't know if that matters.

Comment 1 Michael Schwager 2018-05-06 15:10:24 UTC 
My machine is quite new, btw. I built it yesterday. It's been up for 23 hours 24 minutes and I've been rsync'ing 742G of data to it. Plus I've watched about 1/2 hour of Lord of the Rings in Google Play Movies on Chrome. Which is to say, it certainly seems to be stable as far as I can tell. The error does not seem to be fatal... yet.
Comment 2 Michael Schwager 2018-05-06 15:12:50 UTC 
In the initial description, the lines containing "kiki" are from included from bug #1469488. Sorry for the confusion.
