I can confirm that the dahdi-dkms package in jammy-proposed has fixed the bug for me.
Test done: 1. Modify grub defauls to disable grub hidden timeout, and increase timeout 2. Install linux-generic to have both the kernel in the system 3. reboot to 5.15.0-102-generic kernel 3. Enable jammy-proposed 4. Install digimend-dkms, confirm that the modules builds for both the kernels 5.15.0-102-generic and 6.5.0-21-generic 5. Try modproble of one of the module and check with lsmod $ sudo modprobe dahdi_dynamic_loc $ lsmod | grep dahdi dahdi_dynamic_loc 16384 0 dahdi_dynamic 20480 1 dahdi_dynamic_loc dahdi 258048 1 dahdi_dynamic $ uname -r 5.15.0-102-generic Reboot to 6.5.0-21-generic and try the same $ sudo modprobe dahdi_dynamic_loc $ lsmod | grep dahdi dahdi_dynamic_loc 12288 0 dahdi_dynamic 20480 1 dahdi_dynamic_loc dahdi_transcode 16384 0 dahdi_dummy 12288 0 dahdi 286720 3 dahdi_dummy,dahdi_transcode,dahdi_dynamic $ uname -r 6.5.0-21-generic Test result: the errors with dahdi-dkms has been fixed.
