I also had the issue on the 5.3.0-45 kernel but it happened once for 2 seconds every two days.
It wasn't even noticeable unless you really looked for it. The 5.3 kernel series seems to be a total write off at this point.
While it likely isn't allowed as a solution it might be less effort to back port the focal 5.4.0-28-generic kernel to eoan. I've been on that for several days. Since I upgraded to focal, I've seen no BT kernel panics, no issues with HDMI passthrough audio not working, no i915 hangs or any of the other issues I was seeing on the 5.3.0-x kernels.
