I have a Dell Optiplex 960 that exhibits a reboot during boot with 4.13.0-26 with no kernel panic message (though 4.10.0-42 works fine). I managed to get console dump via serial, which had no information.
Initially I thought it was an out of date BIOS. The machine had A03, so I updated to A17. Still reboots. I tried some other options, such as intel_iommu=off, and no luck. I tried 4.13.0-30 from the proposed repository, and no luck. Finally, I stumbled across bug 1735024. Adding acpi=off worked. Just a suggestion for those having problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742675 Title: after upgrade to linux-image-extra-4.13.0-26-generic the system does not start at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
