[6.72] various crashes in games

[clbr]

Not sure if this is the right place to report, if not, please point to the right place.

On 6.72, I've seen various crashes in games, after hours of play. There's three different crashes, and they don't seem to depend on the game (same crash type happens in multiple games, etc). I'm using commit f06ed109ae4 of sleirsgoevy's repo on a PS4 slim.

1. HDD flood crash
   The HDD begins constantly writing, which heavily drops the game FPS. Saving still works, management UI still works, you can successfully reboot the PS4.

2. Management UI crash
   The game starts to stutter. The management UI has crashed, meaning holding or quick-pressing the PS button does not bring up the management UI. In 10-20s, the console will freeze.

3. Game freeze, unkillable
   The game freezes and becomes unkillable. The management UI still works. Trying to force-close the game spins for 10-20s before the PS4 beeps three times and powers itself down. Trying to reboot the PS4 almost works, it goes to the last stages where the reboot screen turns to black bg from the blue bg, spins there for 10-20s, then PS4 force-powers itself down.
