Dear Maintainer,


    * What led up to the situation?
-> doing apt update and apt upgrade led to installation of kernel
6.13.63. System hangs on reboot then. Tried several times rebooting.


  * What exactly did you do (or not do) that was effective (or ineffective)?
-> booting the last working kernel 6.13.57. Reading out the logs shows a
cored duimp related to Xorg:

user 1000 dumped core.

    * What was the outcome of this action?
-> systems started up again without issues then (with old kernel)

    * What outcome did you expect instead?
-> a working kernel 6.13.63 without any issues.
