#7 suggests a problem with the i801 driver and its interrupt handling. #9 contradicts that a bit, though.

Maybe the C2000 has problems with interrupts, or implements it differently than handled by the driver. This may be triggered by an actual access on the bus. You could try to confirm it by running the i2cdump command after booting without the jc42 module loaded (i2cdetect -y 1 should show no reserved addresses) and see if the interrupts start happening.

Thanks,
