Description of problem:
I have freshly installed Fedora 24 over an Ubuntu installation. Kernel 4.5.7 was installed by an update. When booting Kernel 4.5.7, I get a black screen on boot; I assume the kernel is hung, since the caps-lock key does nothing. The previous kernel, 4.5.5, boots fine.
Version-Release number of selected component (if applicable):
Every time I've tried.
Steps to Reproduce:
1. install kernel 4.5.7 from updates
2. select kernel on boot
black screen, no response from key-presses
System starting normally.
This is a hybrid GPU system (with an NVidia GPU no less), that might be part of the problem.
I don't know what kind of diagnostic information is useful, and guidance would be appreciated.

oops, I think that's for the last successful boot, since it says it's for Kernel 4.5.5 (and the time is wrong).
I got the 4.6 kernel from an update; the problem appears intermittently with 4.6; sometimes it boots OK, and sometimes it doesn't. I haven't found any pattern yet between when it will boot OK and when it won't.
4.5.5 kernel is still booting fine.
As per the Common kernel problems wiki page, I tried removing quiet and rhgb from the boot options, and I still see a black screen. I tried booting without quiet or rhgb, and with boot_delay=1000; this still produces a black screen.
The system behaves slightly differently with boot_delay=1000 specified. Without it, I have to hold the power button down for 5 seconds to restart the system. /With/ boot_delay=1000, as soon as I press the power button, the system powers off (instead of restarting). I don't know if that information is useful at all.
If I haven't mentioned it before, this system is EFI (and it starts in EFI mode).
I'm sorry to keep spamming this, but, the system will boot with acpi=off as a boot parameter. I tried booting the 4.6.3 kernel installed from updates with just that change, and the system came up. (It didn't shut down correctly, but I'm assuming that's because it couldn't power down the system with ACPI off.)
Same here. Asus UX305UA no longer boots after upgrade to 4.5.7-300.fc24.
previously booting 4.5.7-200.fc23.
Just black screen and cpu high.
No hybrid graphics.
acpi=off solves it
seems video related.
i915.modeset=0 always boots
Seems bug 1353103 duplicate.
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. 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'
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 24 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.
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
