Could you provide more detail about how your system is crashing? What part of your system is crashing? Is this a default fiesty install or have installed a custom kernel? I didn't see any oops in your dmesg dump. The only "error" that I can see is the message below
which means AppArmor is denying console access to cupsd, which could possibly cause cups to crash. A possible
quick solution is to to run logprof
> logprof /usr/sbin/cupsd
which should prompt you to add the "a" permission for /dev/tty. Alternately you could also manual edit the profile it should be in "/etc/apparmor.d/usr.sbin.cupsd". You will need to add the line
