Periodic several second freezes with Raspberry Pi 3

You've saved me a lot of time fiddling with multiple SD cards. And I present; a partial fix.

It appears PPSSPP does not get along well with deadline, the default i/o scheduler on Rasbian.

The first step is to change this to cfq. Using sudo, edit /boot/cmdline.txt. Change the text "elevator=deadline" to "elevator=cfq" without changing anything else. Reboot.

Then start PPSSPP, before loading a game, under Settings -> System, change "I/O timing method" to "Host".

You'll still get some hangs, but they will not be as frequent or as long as with the deadline scheduler.
