Hello, as I noticed accidental, the MAC address of the ue0 interface on my rpi 3 is changing between a kernel build with KERNCONF=GENERIC and KERNCONF=GENERIC-NODEBUG from the same revision. It also changes between GENERIC kernels based on different revisions. It looks like the MAC address is stable for each kernel, because when I boot a kernel from an older revision with a known ue0 MAC address this older kernel uses the old known MAC address. I do crosscompiling the rpi3 world and kernel(s) on a amd64 FreeBSD 12.0-Current. The firmware in the FAT partition is not changed between the kernels. As I do not see a common pattern in the MAC addresses, I think they are more or less random memory bits. Examples: d2:8f:50:a0:71:7a GENERIC r324918 de:2a:39:1b:63:1f GENERIC-NODEBUG r324918 7e:45:9d:dc:5b:72 GENERIC r324694 $ uname -a FreeBSD rpi3-b 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r324918: Mon Oct 23 21:46:36 CEST 2017 root@home:/usr/obj/arm64.aarch64/usr/src/sys/GENERIC-NOD EBUG arm64 $ Is anybody experiencing the same behavior?
