Created attachment 258685 [details] stacktrace screenshot Hello! Getting kernel panics on multiple servers. Since it mentions l2tp_core, l2tp_ppp and ppp_generic, I decided to report it to Networking (correct me if I'm wrong). Unfortunately I'm still struggling with making kdump work, so the trace screenshot is all I have at this moment. The only hope is that this stacktrace means something to the guys that wrote the code.
