            Bug ID: 232316
           Summary: Timeout initializing vt_vga panic: page fault
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New

          Assignee: bugs at FreeBSD.org
          Reporter: h2+fbsdports at fsfe.org

Starting a 32bit Linux binary that uses OpenGL causes kernel panic on 12-alpha9
and the nvidia-driver.
