Unable to boot 11.0-release on Unisurf Notebook
I've just bought a Unisurf Notebook[1] and am trying to boot it from a FreeBSD-11.0-RELEASE-amd64-memstick.img. The boot starts OK but hangs whilst probing devices. With safe and verbose enabled, it hangs after complaining about ppc0 (see https://goo.gl/photos/3e7tLWygjsQ6ayBT9). At this point neither Ctrl-Alt-Del nor Ctrl-Alt-Esc have any effect and the only option is to hold the power button down until it powers off. Does anyone have any suggestions on troubleshooting?

Start with: # pkg install gdb # kgdb712 /boot/kernel/kernel /var/crash/vmcore.0 The "712" above is the GDB version number, so it might be different on your system. In GDB: (gdb) bt full Post that output to this list, along with "uname -a".
