Yes. After making initial request as shared, problem solved.
Two more things.

1. My console based on /dev/ttyUSB0 keeps disconnected because /dev/ttyUSB0 changed to /dev/ttyUSB1 back and forward after HDMI controller power on/off.
My TI board has another OTG USB port. May I use it to dump dmesg-message to another machine like netconsole?

2. Does it make sense to increase tasklet priority to make sure it will get call ASAP?

Thanks.
