With the current kernel, it hangs in a state where VIDIOCMCAPTURE always return -EBUSY. After some debug, it seems that VIDIOCMCAPTURE fails the first time because of videobuf_queue_is_busy 'vbuf: busy: buffer #0 mapped'. Then after that error it does a VIDIOCSYNC on all buffer. Then every call of VIDIOCMCAPTURE failed because of check_btres returning -EBUSY. I don't know what cause the first videobuf_queue_is_busy error. But for all the other errors I suppose one of the problem is that VIDIOCSYNC does a STREAMON but never does a STREAMOFF...
