Thank you for your bugreport.

Can you please try the following:

1. Reboot and run "dmesg --level=warn" to check that you're seeing this problem on every boot. If you are still seeing this problem then the "dmesg --level=warn" output should include a backtrace similar to the one from comment 0.

2. If you are still seeing this problem, please run: "sudo grubby --update-kernel=ALL --args=tpm_tis.interrupts=0"; and then reboot (first save any work you may have open).

3. After rebooting run "dmesg --level=warn" again and see the problem still persists.

Please let us know if adding tpm_tis.interrupts=0 to the kernel commandline like this helps.

The upstream kernel developers looking into this have asked for acpidump-s of the laptop models which are known to still have this issues with the latest kernels (Dell XPS 13 9310, Dell XPS 15 9500, Dell Precision 7750).

If you have one of these models please run the following commands:

sudo dnf install acpica-tools
sudo acpidump -o acpidump.hex

And then attach the generated acpidump.hex file here, together with a comment/description for which laptop model it is.

This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 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 Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07.

Fedora Linux 34 is no longer maintained, which means that it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.

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