Troubleshooting • Firmware error in dmesg, and camera not detected

Occasional error (maybe 1/10 boots) with a few errors in DMESG.

[ 4.903248] raspberrypi-firmware soc@107c000000:firmware: Request 0x00030097 returned status 0x80000001

And it also fails to detect the camera (which is an ov64a40 Arducam)

[ 3.876536] ov64a40 10-0036: Error reading reg 0x300a: -121
[ 3.876546] ov64a40 10-0036: Failed to read chip id: -121
[ 3.877085] ov64a40 10-0036: probe with driver ov64a40 failed with error -121

When I reboot, it fixes it, although a couple of times I've had to reboot twice.

I don't know if the two messages could be related?

I'm running with a Raspberry PI 5 4gb (with POE Hat for power)
