Intermittent deadlock while waiting for VSYNC to fall

[jar]

After initialization and upon capturing the first frame with the HM01B0 camera, the code appears to hang on this line [0] while waiting for VSYNC to go low. After device reset, it appears to happen 10-20% of the time. If it passes, it captures frames normally and is not an issue. Might this have something to do with timing and initialization? I increased the delay from 100 ms to 500 ms after reset and it doesn't appear to improve.
