Lock-up with experimental gpu driver (full kms)

This is more of a bug report than a troubleshoot request, but because the whole pi locks up I don't really know where to file it. Basically using xrandr to switch modes followed by mpv to play a file nearly always loks up the pi. My steps to reproduce (probably not all necessary) Install 2017-11-29-...

Getting GPU memory usage

Is there a better way of obtaining GPU memory usage than using `vcdbg reloc`? Since that requires that you flush the cache first, it's not reliable. The vcgencmd mem_reloc_stats and mem_oom commands are useful, but it would be nice to get the usage before we run out. I notice there is a mem_test com...
