Thanks for the extra information.

No, I didn't bisect it.
To add more context here I meant that c1c76700a0d6 ("Merge tag 'spdx-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx") is the first commit that we tested that hit the problem.
The last commit that we tested without this problem is b44f2fd87919 ("Merge tag 'drm-next-2022-08-03' of git://anongit.freedesktop.org/drm/drm") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b44f2fd87919b5ae6e1756d4c7ba2cbba22238e1

I believe this commit is already included in the tree.
We've also reproduced it using latest commit "b2a88c212e65" ("Merge tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b2a88c212e652e94f1e4b635910972ac57ba4e97
Thanks, Bruno
