   As you have a reange of working and non working version, and can as I   
   understand easily reproduce the errors quickly, can you do a bisect?   
      
   I assume in the above this was not present in 6.**12**.57 (6.11.57   
   does not exist). So this would involve compiling and testing a few   
   kernels:   
      
       git clone --single-branch -b linux-6.12.y https://git.kernel   
   org/pub/scm/linux/kernel/git/stable/linux-stable.git   
       cd linux-stable   
       git checkout v6.12.57   
       cp /boot/config-$(uname -r) .config   
       yes '' | make localmodconfig   
       make savedefconfig   
       mv defconfig arch/x86/configs/my_defconfig   
      
       # test 6.12.57 to ensure this is "good"   
       make my_defconfig   
       make -j $(nproc) bindeb-pkg   
       ... install the resulting .deb package and confirm the problem does not   
   exist.   
      
       # test 6.12.63 to ensure this is "bad"   
       git checkout v6.12.63   
       make my_defconfig   
       make -j $(nproc) bindeb-pkg   
       ... install the resulting .deb package and confirm problem is present.   
      
   With that confirmed, the bisection can start:   
      
       git bisect start   
       git bisect good v6.12.57   
       git bisect bad v6.12.63   
      
   In each bisection step git checks out a state between the oldest   
   known-bad and the newest known-good commit. In each step test using:   
      
       make my_defconfig   
       make -j $(nproc) bindeb-pkg   
       ... install, try to boot / verify if problem exists   
      
   and if the problem is hit run:   
      
       git bisect bad   
      
   and if the problem doesn't trigger run:   
      
       git bisect good   
      
   . Please pay attention to always select the just built kernel for   
   booting, it won't always be the default kernel picked up by grub.   
      
   Iterate until git announces to have identified the first bad commit.   
      
   Then provide the output of   
      
       git bisect log   
      
   In the course of the bisection you might have to uninstall previous   
   kernels again to not exhaust the disk space in /boot. Also in the end   
   uninstall all self-built kernels again.
