            Bug ID: 196289
           Summary: Kernel hangs when booting via UEFI
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: kyle@ktdassoff.net

When booting on my system via UEFI mode, loader.efi runs, and I can use the
loader command line. But when it tries to hand control to the kernel, it gets
as far as the spinner character appearing, but then the system completely
hangs. After some time in this state, it will eventually reboot.

CPU: AMD A6-6400K
Motherboard: MSI FM2-A75MA-P33
Firmware version: E7721AMS V11.5

This behavior has been observed both on an installer image running from a USB
memory stick, and from a manually bootstrapped installation on an internal SATA
SSD.
