thanks.

I tested your suggestion with multi_v7_defconfig (32 bit) and arm64/defconfig. The warning disappeared and Ethernet is still working. Only the old issue that we can't receive until a first packet has been send out reappear. But this should be manageable. > > Can you share if this is filed on RPI forum? I didn't submit this to the raspberrypi.org forum / github. They mostly care about the next LTS release 4.19 and not really about arm64. But an Arch Linux user (aarch64 using Mainline kernel) already discovered this issue: https://archlinuxarm.org/forum/viewtopic.php?f=65&t=13302 > Also, it would be appreciated if you can create a ticket on Microchip site at > https://www.microchip.com/technical-support/hot-topics Done Best regards Stefan > > Best Regards, > Woojung >
