Crash-related output of 'dmesg'.
Description of problem:
When running Fedora 26 in gnome-boxes, the virtual guest exhibits frequent crashes due to a bad page state in the host kernel (see backtrace).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot Fedora 26 virtual guest in gnome-boxes.
2. Run firefox.
After using firefox for a short amount of time, the GNOME session crashes and the user is thrown back to the graphical login manager.
Firefox runs without issue.
- After installing kernel-4.12.8-300.fc26 on the Fedora 27 host and rebooting the system, the virtual guest works without any issue.
- The issue cannot be reported by the problem reporting tool because: "The backtrace does not contain enough meaningful function frames to be reported. It is annoying but it does not necessary signalize a problem with your computer. ABRT will not allow you to create a report in a bug tracking system but you can contact kernel maintainers via e-mail.".
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. As kernel maintainers, we try to keep up with bugzilla but due the rate at which the upstream kernel project moves, bugs may be fixed without any indication to us. Due to this, we are doing a mass bug update across all of the Fedora 27 kernel bugs.
Fedora 27 has now been rebased to 4.15.3-300.f27. 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 experience different issues, please open a new bug report for those.
