   Dear Maintainer,   
      
   I've just debugged a new issue with 6.12.69+deb13 vs. 6.12.63+deb13.   
   chrony 4.6.1 (the version in Debian stable) started failing to start   
   with "Fatal error : Could not enable external PHC timestamping".   
      
   We use the extpps mode with PTP hardware clocks. It seems that   
   https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git   
   commit/?id=97529630d85f910f4e6dfc615f1d111ada9448e3   
   changes /dev/ptp* to now require FDs open for writing to configure   
   extpps. Chrony has a fix   
   (https://gitlab.com/chrony/chrony/-/commit/f78e4681eff71d941fab3   
   e5ee406d920a155a20),   
   but that's only in the version in testing/sid.
