Screenshot from crashed laptop

1. Please describe the problem:

Recent update included kernel 5.8.15-101 which causes the system to freeze on boot. Rolled back to 5.5.10-200.fc31.x86_64 and system can boot again

Laptop is a Dell Latitude 7285 with a reasonably vanilla install of Fedora 31.

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

kernel-5.8.15-101.fc31.x86_64

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 :

5.8.13-100.fc31


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


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 at this stage.

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 will attach a screenshot of the lock when booting with a debug kernel. I can't easily grab a kernel log due to the early stage where the log occurs.

One of the key errors is

can’t change power state from D3cold to D0 (config space inaccessible)`, stuck at boot
Comment 1 Ben Cotton 2020-11-03 16:59:59 UTC 
This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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' of '31'.

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 31 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.
Comment 2 Ben Cotton 2020-11-24 17:24:41 UTC 
Fedora 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 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
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
