Created attachment 1139940 [details] Successful (kernel 4.4.3) Xorg.log I have an HP laptop, and I'm running Fedora 23 with various DMs and DEs. Currently LightDM and MATE, but it has seen GDM, and Plasma 5, XFCE, all of which show the exact same problem. With the newer kernels (4.4.4 and above) the machine boots, switches to the DM, and I can interact with it just fine, but the moment I log in to any of the mentioned desktops, the machine locks up hard: the mouse cursor doesn't move even. With 4.4.3 everything works fine. Here's my fpaste --sysinfo: http://paste.fedoraproject.org/344530/45881575/ The only significant difference between the Xorg.logs is the last two lines, where the machine doesn't lock up, it will say: (II) intel(0): resizing framebuffer to 3840x1369 (II) intel(0): switch to mode 1920x1080 on eDP1 using pipe 0, position (1920, 289), rotation normal, reflection none

Please test 4.4.6. There were known bugs fixed there.
I wish I could pin 4.4.3 to stay so any other kernels get replaced but I always have one version that is known to work -- AFAIK this is only possible with yum (`yumdb set installonly keep ...`) and not possible with dnf, right? I'll extend the number of kept kernel images in dnf.conf and will give 4.4.6 a try when I can

No, that is not correct. If you boot into 4.4.3 on your machine and install 4.4.6, dnf should refuse to remove 4.4.3 because it is the currently running kernel. It will remove a kernel older/newer than 4.4.3 kernel instead. > I'll extend the number of kept kernel images in dnf.conf and will give 4.4.6 > a try when I can That's another possibility but it should not be required.
4.4.6 appears to work, thank you.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. 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 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those.
As I said in the previous comment, 4.4.6 appeared to work at the time. The issue has not resurfaced since.
Thank you again.
