Description of problem: After choosing the kernel to boot in GRUB, if it is later than 4.10, then after showing the message "EFI stub: UEFI secure boot is enabled", the computer freezes. No further activity takes place, and it is unresponsive to key-presses. Version-Release number of selected component (if applicable): Any later than 4.10. For example, the current latest 4.11.10-200.fc25 How reproducible: Every time Steps to Reproduce: 1. Boot into 4.11.x kernel Actual results: Freezes Expected results: Boots Additional info: The CPU model name in /proc/cpuinfo is "Intel (R) Pentium(R) CPU N3540 @ 1.26GHz", with cpu family 6, model 55. The machine is an Asus Laptop, model number E402M. I waited for a while before reporting it (there have been a few 4.11 kernels) in case it got fixed in the mean-time. But it's been some weeks now, so I am reporting it.
I upgraded the machine to Fedora 26. Attempting to boot with the Fedora 26 kernel, it gets further into the boot process (if I remove 'rhgb' and 'quiet' from the kernel command line, then lots of things scroll past), but it still locks up during the boot process. The Fedora 25 kernel allows it to boot into userspace.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Eventually, a few months after the problem began, latest kernels began working on this machine again. All is well. This bug report continues my long, unhappy tradition of posting stuff in Bugzilla with accompanying detail and willingness to provide whatever's needed, and getting zero response of any sort. I appreciate all your work and benefit from it daily. If I'm doing something wrong I'd be happy to be corrected.

There is no good answer for you other than your bug is one of several hundred reported against the kernel and it didn't map to a larger theme seen among them. There have been only 2 maintainers for a while now, and they can't reply to every bug or they would do nothing else. This is unfortunate from a user experience standpoint, but it is reality. Please keep reporting.
