Thanks, that's interesting. I guess the next steps would be to try and work out what's different between your two setups. - same board revision? - same firmware/ATF? - same kernel/modules? - same type of link partner? (I suspect, given the cpu-pd-wait interaction, isn't the problem.) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
