Please excuse URL mangling, my bugzilla address appears to route through

kernel.log, config, cpuinfo

I'm getting a deadlock and the computer is unresponsive shortly after setting
up a xl2tpd/ipsec vpn connection. The deadlock occurs every time, it is very
reproducible on my computer.

It is the mainline kernel, version 4.3.2.

The processor is given in a copy /proc/cpuinfo that I've attached.

uname:
Linux version 4.3.2 (gcc version 5.3.1 20160121 (Debian 5.3.1-7) ) #5 SMP
PREEMPT Sat Jan 30 00:05:40 CET 2016

ppp is from the debian package of their unstable distribution:
ppp_2.4.7-1+2_amd64

I've attached the kernel config file and the kernel log.
