Tailscale error crashing Ubuntu 22.04.4

[dlange82]

What is the issue?

Tailscale is crashing linux system, latest kernel version on a Raspberry pi 4, Ubuntu 22.04.4.
We run a gstreamer pipeline for streaming video over a webrtc session using go. The load is 50-60% on all CPUs. Memory is 450MB. Memtest and CPU stress tests without errors.

After updating from 1.60.1 to 1.64.0 we experienced kernel errors crashing the pi. After upgrading to 1.66.1, the following error is thrown.
