X204e card driver causes reboot loop on PBX server

I am configuring the OpenVox X204 card with a B200M module and an FXS200M module on a Dell r230 system, running FreePBX distro (SNG7-PBX-64bit-1712-2, released on December '17).
I installed the DAHDi kernel modules following the guidelines from the manual
The kernel modules were successfully loaded the first time, and the span ports were listed on FreePBX webui.
Nevertheless, when reloading the dahdi modules, the system fails to recognize the FXS module. This is easily reproduced by running, which will show the following errors during module load:
Also, when i try to reboot (i.e. simple restart, without shutdown), the system enters a reboot loop. Escaping the boot loop is only possible by cold booting the server (e.g. using power button). This one does not leave a log trail, but i managed to pin-down the issue on loading of the x200 module, by doing the following:
Both issues are independently reproducable on my machine. Any ideas on how to fix?
Thank you,
EDIT: I reached a point where i can reboot the server without entering a reboot loop. Before issuing the reboot command, i made sure to first unload the modules, runningTo my understanding this ensures a proper card detach, which yields the following kernel log entries:Uppon loading the drivers no reboot is caused and the fxs200m driver is loaded correctly as well. So it seems that unloading dahdi modules is required prior to a reboot, at least on my setup.
