            Bug ID: 191206
           Summary: [drm] radeon or i915 freezes console on UEFI amd64
                    system
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: dch at skunkwerks.at

FreeBSD installs for the first time on this UEFI-only MacBook Pro from 2011
using
http://ftp.at.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/11.0/FreeBSD-11.0-CURRENT-amd64-VT-20140614-r267488-memstick-uefi.img.xz

Following steps in https://www.freebsd.org/doc/handbook/x-config.html the
console freezes when startx is run after either i915kms or radeonkms driver is
loaded. The mouse pointer is still visible on the console, but its frozen
completely.

System is still running, and accessible e.g. over ssh. Remote access can be
organised if there's a need.
