Using vanilla kernel and only DVB-T stick and RAID runs rock solid. I have used this setup for years (first Raspbian, since ~ 1 year aarch64). 1.5 months ago I started a new project on my rpi: communication with my solar inverter and battery. Because there were many changes in the beginning of the project Iand there are overlapping issues I cannt remember perfectly. First I used onbiard RS232 (GPIO14/15) and I think there was no issue except the one I have to power down and up RAID if I reboot rpi. That bothers so I switched to rpi kernel. Now there was no need for powering down - RAID was recognized stable at a reboot. But RS232 vanished and I could not bring it back again. Now I added a FTDI - and then (I think) freezing started. 10 days later (sure freezing was before that) I added RS485. Since then there passed a few kernels, and as I already stated there were some which looks better than others in stability. But I have had none which was solid.$this->bbcode_second_pass_code('', 'lsusb -t
