I did disable the Cool 'n' quiet mode, and the system has not locked up since ... I will continue to test. So at this point I am not certain if this is related to the NVidia drivers, or not. I didn't have the problem until I enabled the video driver, but perhaps that was a coincidence, or perhaps running the nvidia driver was just enough of a load on the processor to cause the CPU stepping. Maybe it was the combination of the 3.
Either way it is looking like this issue may primarily be related to the kernel. I would really like to be able to better determine the root cause. If I can provide any further information please ask. -- [nvidia-glx] system frequently locks up with white screen with black lines while nvidia restricted driver in use must hard boot system https://bugs.launchpad.net/bugs/109643 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
