While at first the easy fix to this issue would be "Don't remove modem",
sometimes it resets itself and therefore appears to disconnect and reconnect
which causes the system crash.

I can reproduce the problem 80% of the time by ripping the modem out of the
USB port. However, if I kill -9 pppd before doing it, it never happens so the
problem appears to be an interaction between pppd and the kernel. As full
system lockups in my limited knowledge must be kernel problems since systems
should never fully lock (with flashing caps lock and scroll lock lights, not
responsive to magic sysreq keys) presumably this is a kernel bug.

It also did not happen until recently, some point within the last month. I
would have reported it earlier (and reverted to a kernel that didn't do it)
but didn't realise why it was happening.

If I can provide more information to help then I will do my best.

Possibly relevant is I connect to the internet with a udev rule:

SUBSYSTEM=="tty", SUBSYSTEMS=="usb", DRIVERS=="option",
ATTRS{bInterfaceNumber}=="00", NAME="hsdpa", RUN+="/usr/bin/wvdial
&>/dev/null&"

Keywords: networking, pppd, kernel, crash
