(That NoIR Raspberry camera module locks up kernel but that is offtopic here.)

This issue is new to me, please report to the list.

News to me too, I have a standard camera module attached to a 3A without issue. Lets start a different thread on this.

It is a Camera V2.1, there was connected other camera on USB during boot, dmesg shows with the Raspberry Camera additionally just:

bcm2835-v4l2: scene mode selected 0, was 0 bcm2835-v4l2: V4L2 device registered as video2 - stills mode > 1280x720 bcm2835-v4l2: Broadcom 2835 MMAL video capture ver 0.0.2 loaded. bcm2835-v4l2: Failed to enable capture port - error -1. Disabling camera port again

More dumps below.
