In tx2,there is no video after the restart of camera during the video capture

Hello,

In tx2,there is no video after the restart of camera during the video capture.
I restart the application and then get video. But this problem doesn’t happen on the tx1.

I think the kernel source of tx2 might have a bug.I think that the vi tegra channel don’t reset normally.
The function tegra_channel_error_worker() I trace by checking the code only have vi4_power_off() and don’t have vi4_power_on(). I think it’s the reson of my problem.

I will be grateful for any of your suggestions.
