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Initially I thought it was an out of date BIOS.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.
