Log of kernel messages at a normal boot

1. Please describe the problem:

After upgrading to kernel-5.3.12-300.fc31 I do not get a LUKS password prompt at boot and the entire PC hangs with a blank screen. This behaviour is reproducible with kernel-5.3.13-300.fc31 as well.

If I reboot to an earlier kernel (kernel-5.3.11-300.fc31), the system asks for the LUKS password at boot and boots up fine.


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

kernel-5.3.12-300.fc31 and kernel-5.3.13-300.fc31

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 :

kernel-5.3.12-300.fc31


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

* Reboot from a kernel-5.3.11-300.fc31 after upgrading to the kernel-5.3.12-300.fc31.
* Select kernel-5.3.12-300.fc31 at boot
* System shows a blank screen and hangs, instead of displaying a LUKS password prompt.


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``:

Not tested. But the latest kernel update kernel-5.3.13-300.fc31 also causes the same problem.


6. Are you running any modules that not shippekernel-5.3.13-300.fc31d 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'm unable to attach kernel logs because the boot is not logged. System hangs without displaying a LUKS password prompt and therefore nothing is logged.
