I don't see any successfully probed ethernet devices in the boot log, so I've no idea which of the multitude of ethernet drivers to look at. I thought maybe I could look at the DT, but I've no idea where "arm/bcm2837-rpi-3-b-plus.dts" is located, included by arch/arm64/boot/dts/broadcom/bcm2837-rpi-3-b-plus.dts. The oops is because the PHY state machine has been started, but there is no phydev->adjust_link set. Can't say much more than that without knowing what the driver is doing. > > Thanks, > Daniel > > > [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] > [ 0.000000] Linux version 5.3.6 (wagi@beryllium) (gcc version 9.2.1 20190827 (Red Hat Cross 9.2.1-1) (GCC)) #16 SMP PREEMPT Mon Oct 14 14:36:09 CEST 2019 > [ 0.000000] Machine model: Raspberry Pi 3 Model B+ > [ 0.000000] efi: Getting EFI parameters from FDT: > [ 0.000000] efi: UEFI not found. > [ 0.000000] cma: Reserved 32 MiB at 0x0000000039400000 > [ 0.000000] NUMA: No NUMA configuration found > [ 0.000000] NUMA: Faking a node at [mem 0x0000000000000000-0x000000003b3fffff] > [ 0.000000] NUMA: NODE_DATA [mem 0x3920d840-0x3920efff] > [ 0.000000] Zone ranges: > [ 0.000000] DMA32 [mem 0x0000000000000000-0x000000003b3fffff] > [ 0.000000] Normal empty > [ 0.000000] Movable zone start for each node > [ 0.000000] Early memory node ranges > [ 0.000000] node 0: [mem 0x0000000000000000-0x000000003b3fffff] > [ 0.000000] Initmem setup node 0 [mem 0x0000000000000000-0x000000003b3fffff] > [ 0.000000] percpu: Embedded 22 pages/cpu s52632 r8192 d29288 u90112 > [ 0.000000] Detected VIPT I-cache on CPU0 > [ 0.000000] CPU features: detected: ARM erratum 845719 > [ 0.000000] CPU features: detected: ARM erratum 843419 > [ 0.000000] Built 1 zonelists, mobility grouping on.
