I having a very ticklish question, I open the ipu channel through calli the ipuv3 driver(through the function static int capture_open(struct inode *inode, struct file *file)), the linux kernel is halt without any trace log, show the message:
enter ipu_err_irq_handler.IRQ:37
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00000001
later the kernel is halt, I have to power off and power on to restart the system.I can't understand the problem, please help me. thank you very much!


ps:my kernel is linux 3.14.52
