Apparently this is not a bug that is only related to Ubuntu but to other flavors as well, see https://bugs.freedesktop.org/show_bug.cgi?id=75394. This could possibly be marked as a duplicate of that bug. One further note I am still experiencing the lockups with the above error noted. If it makes any difference I've added drm.debug=0x06 to my /etc/default/grub file and rebooted. I will attache the output of dmesg to this bug report for reference.
