Good news: version 4.11.5 of the kernel fixes this problem for me. I upgraded using this command:

sudo dnf update --enablerepo=updates-testing kernel

Do you see anything useful if you press "e" from the GRUB menu and then remove "quiet" from the boot parameters?

What kind of video card do you have?

This is probably related to https://bugzilla.redhat.com/show_bug.... .

Version 4.11.5 of the kernel will be released soon and should fix the problem you are having. If you need the fix immediately, see https://fedoraproject.org/wiki/QA:Upd... for instructions on how to install test updates.

You're welcome. Are you able to edit the title of this post? Could you change it to something that will help other people find it? For example,

Kernel panic in version 4.11.3 using nouveau driver

I was also able to work around this problem by disabling the nouveau video driver (I'm using my motherboard's built-in video instead of my Nvidia card.)

  1. Switch to superuser with sudo -i.
  2. Add modprobe.blacklist=nouveau to GRUB_CMDLINE_LINUX in /etc/default/grub.
  3. Run grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg.
  4. Reboot.

I have reported this to Red Hat as bug #1460456:

Would you please post the output of lspci on your computer?

Are you able to capture a kernel core dump?

  1. Switch to superuser with sudo -i.
  2. Add crashkernel=128M to GRUB_CMDLINE_LINUX in /etc/default/grub.
  3. Run grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg.
  4. Run systemctl enable kdump.
  5. Reboot into your good kernel.
  6. Run systemctl status kdump and look for errors.
  7. If kdump reports no errors, reboot into your bad kernel and wait 60 seconds after the kernel panic.
  8. Reboot into your good kernel and see if there are files under /var/crash.

I can reproduce this bug 100% of the time with 4.11.3-200.fc25 and 4.11.3.202.fc25. I have screenshots of the kernel stack trace here:

If you look at the top of the stack trace in the first image, you can see the unhandled kernel paging request occurs immediately after lines that begin with fbcon, which makes me think the bug is in the video subsystem.

To work around this problem:

  1. Press e at the boot menu.
  2. Delete the word quiet from the line that begins with linuxefi.
  3. Press Control+X to continue the boot process.

Here is my hardware:

I was unable to get a core dump by following the instructions in https://ask.fedoraproject.org/en/ques... because adding crashkernel=128M to the boot parameters prevents the crash from happening.
