Is anyone else finding that their 5D3 goes to sleep in the middle of recording? I've formatted my 32Gb Lexar 1000x CF card as exFAT and enabled >4Gb recording, and the longest recording I've managed (at 1928x1080 raw) before the screen shuts down and the mirror locks back into place is 5,159,790,912 bytes (5.16Gb). Hitting the start/stop button wakes the camera back up, but it's as if it's doing a full boot from shutdown as far as Magic Lantern is concerned (I see the card speed test happen, and then I have to go re-enable the modules and configure raw and audio before recording).
I'm not sure what's going on. Maybe somehow ML is taking over to such an extent that the Camera OS doesn't know there's activity going on, so it goes to sleep? It happens every time.
It's amazing how quickly this hack is developing into a useful feature, btw.
