  [ Test case ]
  
  Install the latest linux-6.14 kernel on Noble:
  
  $ sudo add-apt-repository ppa:canonical-kernel-team/ppa
  $ sudo apt install linux-generic-hwe-24.04-wip
  
  Install sl-modem-dkms
  
  $ sudo apt install sl-modem-dkms
  
  Load the modules:
  
- $ sudo modprobe
+ $ sudo modprobe slusb
+ $ sudo modprobe ungrab-winmodem
  
  The same procedure can be repeated on linux-6.8 to test for possible
  regressions.
  
  [ Fix ]
  
+ Apply patch from Debian (https://salsa.debian.org/debian/sl-
+ modem/-/blob/master/debian/patches/fix-linux-6.12-ftbfs.patch):
+ 
+ * debian/patches/fix-linux-6.12-ftbfs.patch
  
  [ Regression potential ]
  
  We may experience regressions in systems that are using the sl-modem
  drivers, especially with kernels >= 6.8 kernel.
