I am running Armbian Focal with Linux 5.4.43-sunxi64 (and now downgraded to 4.19.125-sunxi64) on my Orange Pi PC 2. I use motion software to provide a "18ec:5555 Arkmicro Technologies Inc.

As soon as I start pjsip for some reason I get a very high load average until the kernel detectets stalled CPUs and finally the entire device crashes. This worked fine in a previous version and started after I upgraded to focal. I did a kernel backtrace and this is what I got:
Does anybody know what might be going on here and how I can fix this issue? Or do I need to go back to Ubuntu Bionic with Armbian Linux 4.13.2-sun50iw2 which I was running before?
