In general kernel oopses are kernel bugs, not userspace bugs, so
reassigning to linux.  I expect that the full contents of the oops
message from syslog would be helpful to the kernel maintainers.

Right, we can't do anything useful without that.

Also, are you using the on-board Ethernet or a separate adapter in the
RockPro64?

You'll need to capture the kernel log using a serial console
<https://www.kernel.org/doc/html/latest/admin-guide/serial-console.html>
or netconsole
<https://www.kernel.org/doc/html/latest/networking/netconsole.html>.
