Summary0016749: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
DescriptionGnome desktop performing a gui Bacula Differential backup to an external e-sata drive. Running one terminal login, Firefox open minimized, and Evolution mail open normal. Suddenly, the system clock seconds stopped. The screen went to console, an approximately 4 by 4 inch color checkerboard appeared just down from the top left corner where some "crash" type messages were written, about 4 or 5 more "crash" type messages overwrote the checkerboard, the screen went blank and the system rebooted normally.
Steps To ReproduceNot really sure I can. This happened before when I had a tainted prior kernel from out-of-tree, unsigned modules which I have since resolved.
Additional Information No crashes happened with my Centos 6 installation. Please advise as to what additional information is necessary.
