The error implies that duplicate > opps are reported by the SCP firmware and appear once during probe. I only see it at boot, but it shows up four times here with the CRD: [ 8.098452] arm-scmi arm-scmi.0.auto: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16 [ 8.109647] arm-scmi arm-scmi.0.auto: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16 [ 8.128970] arm-scmi arm-scmi.0.auto: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16 [ 8.142455] arm-scmi arm-scmi.0.auto: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16 > This particular error can be fixed only by a firmware update and you > should be able to test it out soon on the CRD first. Can you explain why this can only be fixed by a firmware update? Why can't we suppress these warnings as well, like we did for the other warnings related to the duplicate entries? IIUC the firmware is not really broken, but rather describes a feature that Linux does not (yet) support, right? Johan
