            Bug ID: 277268
           Summary: RPi4: LOR in gpioled(4)
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: arm64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: arm
          Assignee: freebsd-arm@FreeBSD.org
          Reporter: lexi.freebsd@le-fay.org

while booting, the kernel reports a LOR in gpioled(4).  the system appears to
work fine aside from this (i am not using the LED driver).
