Note9 has 12 D state processes.

[etbe]

My note9 has kernel threads [simpleinteracti]*9, [tee_irq_bh], [tee_scheduler], and [exynos_hpgov] in D state after a fresh install of Droidian.

This happens immediately after a reboot when USB is not connected. So the rndis0 issue is not causing this.

I also have the stylus not working with a mouse cursor permanently on screen, is "simpleinteracti" something related to the stylus?

Below is the output of ps, the PID numbers suggest that it didn't happen immediately on boot but after 2000 processes had been used in the system startup.

Below is the first kernel panic shown in the output of "journalctl -b".
