It appears that at some point the nouveau driver may have been updated. Possibly when I installed mainline 4.17rc4 Kernel in recovery mode with network enabled. System no longer randomly locks up when booted in to kernel 4.15.
After installing Nvidia 396 driver and one final hard power off the OS will shutdown/restart successfully in 4.17 kernel at least. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769376 Title: NMI watchdog: Watchdog detected hard LOCKUP on cpu x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1769376/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
