greetings and a question on loading pppd after an upgrade to kernel 4.1.7+

[robert rottermann]

Hi there,

this is my first post on this mailing list and I wonder whether this the rigth
place to ask the following question. If not would you kindly point me to the
correct list.
thanks

After doing an apt updated which installed the kernel 4.1.7+ I can not lod the
pppd deamon anymore. I get the following error:
Couldn't open the /dev/ppp device: No such device or address
/usr/sbin/pppd: Please load the ppp_generic kernel module.

what could be the reason for this?

if I try modprobe ppp_generic
I get:
ERROR: could not insert 'ppp_generic': Exec format error


some background:
for a project involving a modem I need to compile the n_gsm.ko module.
I had to recompile it for the new kernel. To do so I installed rpi-source and
added the line:

|deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free
rpi to ||sudo nano /etc/apt/sources.list.d/jessie.list |

what can I do to load ppp_generic?

thanks for your help
robert
