Hi!, i got some issue with armbian version 20.11. The problem is similar to https://forum.armbian.com/topic/2076-a20-cubieboard-2/ . I tried to blacklist the ir, too. But it do not fix my problem, because there were changes at the commands to blacklist the ir. But also i am not 100% sure that it is the ir, because the prompt shows me the stacks and pointed at the smbd PID (at the appendix - fotos). (Sorry for the bad foto quality!) I appreciate your help! Thank you !
