OrangePI ONE swich to alternative karnel problem

[Fumio-Koitabashi]

Hi

1. In OrangePI ONE, when you execute swich to alternative karnel (next) Swich to display resolution item is gone, it does not become usable.

Currently, swich to alternative karnel (next) is executed

2. When gqrx - sdr modifies blacklist.conf, the following error appears. (I think it is a problem of kernel)

Kernel driver is active, or device is held by second instance of librtlsdr. In the first case, please either detach or blacklist the kernel module (dvb_usb_rtl 28 x x u), or enable automatic detaching at compile time.

Trying to fill up 1 missing channel (s) with null source (s). This is being done done to prevent the application from crashing due to gnuradio bug # 528.
