Answering to note 7, >From 12 boot sequences (there was 2 seconds waiting in power-off mode before starting the next boot), the results where:
Kernel 4.4.0-83.106 crashed on boot (with the same error) 5 out of 6 times. Kernel 4.4.76-040476 crashed 0 (zero) out of 6 times. Looking good for 4.4.76-040476! PS: No errors while installing kernel 4.4.76-040476, and virtualbox seems fine running too, although not relevant for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1703091 Title: Kernel panic - not syncing: Fatal exception in interrupt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1703091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
