1. Please describe the problem:

Updated to latest updates-testing, which also includes https://bodhi.fedoraproject.org/updates/FEDORA-2026-63df5a1660 (not entirely sure whether it's related) and kernel started emitting a trace

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

7.2.6-200.fc44.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 :

I did not see this trace before with this or any other kernel.

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

Boot the kernel on ThinkPad T14s Gen 7 Intel, with alsa-sof-firmware-2026.09-1.fc44 installed?

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``:

Did not try.

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.
