            Bug ID: 271147
           Summary: Adding support for Sunrise Point uart hangs boot
           Product: Base System
           Version: 13.2-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: marcus@FreeBSD.org

I regularly track -STABLE on this small form factor machine I use as a router. 
After upgrading on April 29 (last was April 23) the machine hung on boot just
before polling the ISA bus.  I tracked the commit down to
 Specifically, adding support for the Intel Sunrise Point Controller 0 (which
this machine has).  Removing this line restores normal booting.

Attached are my dmesg and pciconf output.  I'm not sure if perhaps this
controller needs a quirk...?
