            Bug ID: 222079
           Summary: [ichwd] New Intel TCO Watchdog Timer (Skylake/Sunrise
                    Point and newer) is not supported
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: greg at unrelenting.technology

Looks like Intel moved the watchdog from LPC to SMBus in Sunrise Point, so the
ichwd driver does not work anymore.
