@Joseph for a long time i've also got such kernel issues: in fact booting was failing each time the first time (was affected many kernels accross a year or so) with various crash messages.
And finally i've found that these issues was due to ram voltage set too low by the default bios setting. I then searched for the ram model stick specs and what voltage should be affected to it. So i've unhide the ram voltage (bios AMI) by setting the cpu on "manual" but nothing changed on the cpu settings side (no tweaks), then the ram voltage have been set on "manual" too with the required 1.85v for the ram sticks. Since i've never had issue to boot: no kernel panic, no pointer trouble, .... If the bios have to be blamed on my system when booting ubuntu/linux, the same system was not having trouble to boot windows. So there is a problem on the linux kernel, wanting too much power. nb: i suppose there is tons of 'kernel panic, or else') reports due to the problem i've found. So it might be important to dig around that issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1495639 Title: Bug: unable to handle kernel NULL pointer dereference at To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1495639/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
