Problem also seen with 3.14.8-200 Well, I'm now on to 3.15.10 and the previous few fc20 kernel updates have been fine. So this problem has "gone away". Has someone fixed it? Please reply if so and formally close the bug. Or is there still some latent gremlin waiting to jump out at us again? It may well be fixed. It may also just be hidden due to a different address layout or something similar. There are around 10000 commits per major kernel release and we can't possibly track them all. For now, we'll close this as WORKSFORME and if you see it again please reopen the bug. |
Created attachment 908934 [details] Output of /proc/cpuinfo Description of problem: On booting, the kernel immediately reports a Machine Check Exception and hangs, then reboots after 30 seconds. Versions: kernel-3.14.6-200 and 3.14.7-200 kernel-PAE-3.14.6-200 and 3.14.7-200 This does NOT occur with versions 3.14.5 or 3.14.4 How reproducible: 100% failure with 3.14.[67] 100% success with 3.14.[45] Steps to Reproduce: 1. Upgrade to kernel 3.14.7-200 2. Boot from 3.14.7-200 kernel. 3. Immediate failure as described. Actual results: Machine check exception reported and kernel does not continue boot, and then attempts reboot after 30 seconds Expected results: Normal boot sequence of kernel Additional info: The system is a Gigabyte J1800 D2H. Details from /proc/cpuinfo attached. I would like to attach the actual MCE, but I haven't been able to extract the info from mcelog. I might need some guidance on doing this. I can boot from 3.14.5 just fine, so "high" priority, rather than urgent.
