crash log

1. Please describe the problem:
kernel crashes when trying to login in GDM

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

5.12.5-300.fc34.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 :

GDM login works fine with the kernel from Fedora 33 ( 5.11.21-200.fc33.x86_64 ) .

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

yes

- start Fedora 34
- press enter to login on currently selected user

At this point the crash happens (i never reach the point where i can enter password, or select a different GUI session like XFCE).


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``:
-N/A

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

As far as i know i am not running any modules that not shipped with directly Fedora's kernel.

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.
