OpenGL Freeze (RetroArch)

[loganmc10]

I am trying to launch an N64 game in RetroArch using the new OpenGL Driver. It locks up, once it does, I can SSH into a new session, but all sorts of commands lock up, including /opt/vc/bin/vcgencmd

This is the GDB backtrace:

I have to reboot to get things like /opt/vc/bin/vcgencmd to work again
