Hi Geert, this was detected by kismet tool developed by Paul Gazzillo and Necip Fazil Yildiran.
It can be obtained at [1]

And the issue detected by it can be reproduced by make olddefconfig as well,
the detail can refer to the reproduce instruction [2]

I give a try as below inside mainline repo

$ git checkout ccc4e6a061a21d75b96d82fc4b084a8d96df6eb4
$ wget https://download.01.org/0day-ci/archive/20231106/202311062309.XugQH7AH-lkp@xxxxxxxxx/config -O .config
$ $ make ARCH=arm olddefconfig
