foto of kernel panic stack trace

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0a2) Gecko/20110819
Firefox/8.0a2

today systemd suddenly stopped working, initially i found out that the network
went down, however upon examination why that happened i discovered _lots_ of
zomie processes(dbus-daemon, wpa_supplicant, udisks,...), all of them were
children of the init process (systemd).

knowing that the init process should clean up such zombies i thought i attach
with gdb and get a backtrace of the hang... well that turned out to be
impossible because gdb pretended the process was already being debugged.

gdb asked to kill the process and stupid as i was i answered yes: -> kernel
panic xD
I'm not sure the backtrace i have is of use, but I don't have more =/

a few hours before i did a zypper dup that also updated systemd from 33.x to
33.y IIRC

Kernel panic - not syncing: Attempted to kill init!
