Description of problem: Spontaneous reset a few minutes after boot, "machine check events logged" in Problem Reporting tool Version-Release number of selected component (if applicable): kernel-4.13.5-200.fc26.x86_64 and kernel-4.13.4-200.fc26.x86_64 How reproducible: Always Steps to Reproduce: 1. Boot 2. Login to GNOME 3. Wait for 5-15 minutes 4. PC reboots without warning Actual results: mce: [Hardware Error]: Machine check events logged Expected results: No spontaneous reset. Additional info: I'm on an AMD Ryzen 1700 processor. The Problem Reporting tool is hard to get info from, but I can attach whatever fields from the kerneloops you find interesting. I see that mcelog doesn't support AMD processors, or at least mine, so there doesn't seem to be a lot of info. This didn't happen on 4.12 and previous kernels - just severe lags when doing heavy file copying, but I suspect that's because of AMD's hyperthreading, as I've seen some articles mentioning it as a problem. Thank you for your time.
Hello, Thanks for the bug report. Can you reproduce this with the latest kernel-debug and attach the oops message?
I've installed the debug kernel for 4.13.5-200, and it hasn't rebooted yet (been up for around an hour). Not sure what's going on. I've even installed the "stress" package, but it doesn't seem to be rebooting now. Sorry if I've wasted your time.
I've uploaded what I see in Problem Reporting, if it's useful let me know and I'll copy all of the info in: https://imgur.com/KK4lNBu https://imgur.com/YAxXStU
This is happening again on 4.13.11-200 (the reboots) and I've reinstalled kernel-debug (I had removed it for lack of space on /boot). I'm also seeing errors on my boot log. Here's dmesg's relevant output: ...

We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs. Fedora 26 has now been rebased to 4.15.4-200.fc26. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 27, and are still experiencing this issue, please change the version to Fedora 27. If you experience different issues, please open a new bug report for those.
No need to apologize. I've tested the 4.15 kernels on F27 and the problems are gone. Thanks!
