journalctl -b -1 --no-hostname -k

1. Please describe the problem:

I upgraded F34 to the latest kernel (5.14.14) and rebooted. When the computer reaches the login screen it completely freezes. Both the keyboard and mouse are unresponsive and I can't log in (or do anything else).

2. What is the Version-Release number of the kernel:

broken kernel: 5.14.14-200

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Yes, keyboard and mouse used to work. They continue to work if I boot into 5.14.11-200.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Boot into the latest kernel and wait for the screen to freeze.

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:


6. Are you running any modules that not shipped with directly Fedora's kernel?:

No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

I think I've attached the right file, dmesg.txt.
