Description

Tested kernel 4.18.10-200. Unfortunately ethernet is still broken. Tested kernel 4.18.13-200. Ethernet is still broken. Last working kernel was 4.18.0-0.rc0.git2.1.fc29. I have this same issue with my wandboard quad. The only information I can add is that if I stop the boot process and get a uboot prompt then try to boot from the network Uboot is able to obtain an IP address. The kernel is not able to do this. I can reproduce, the issue is now to work out what caused the regression. So there's a couple of things coming into play here. There was a bug in the 4.18 cycle that caused boot issues with ARMv7 due to BPF JIT which causes an issue on the device, but when that kernel is built with BPF JIT disabled networking works fine. So for this actual problem the rc0.git[3-5].1 kernels are fine. Just building/testing kernels with the bpf jit disabled to work out which is the first kernel where this actually stopped working so I can then bisect it from there. Interestingly also a i.MX^sx device works just fine (In reply to Peter Robinson from comment #7) > Interestingly also a i.MX^sx device works just fine i.MX6sx even. So the regression happened first with the 4.18.0-0.rc0.git10.1.fc29 kernel. Which for reference is somewhere in the upstream commit range of 2837461dbe6f4a9acc0d86f88825888109211c99..4c5e8fc62d6a63065eeae80808c498d1dcfea4f4 This is fixed in the 4.18.16 kernel. Please test. For reference, in 4.18 the OF_MDIO/MDIO_DEVICE/FIXED_PHY/PHYLIB driver components were fixed to build modular so we moved them from built in to modular. It seems the micrel PHY used in some imx6 devices works fine when using the above bits built modular but the at803x used by Hummingboard/Wandboard and friends doesn't. I've reverted to building it back into the kernel until I can engage with upstream to get it fixed. Confirmed. Kernel 4.18.16 fixes Ethernet bug 1628209 on my Wandboard Quad. Thanks for the fix! Proposed as a Freeze Exception for 29-final by Fedora user pbrobinson using the blocker tracking app because: imx6 is a key ARMv7 SoC with numerous devices, including widely used Wandboard and Cubox-i kernel-headers-4.18.16-300.fc29 kernel-4.18.16-300.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-dbea673f8a kernel-headers-4.18.16-200.fc28 kernel-4.18.16-200.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-2a2a5be13c kernel-headers-4.18.16-100.fc27 kernel-4.18.16-100.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2018-edf9c345c3 Discussed during the 2018-10-22 blocker review meeting: [1] The decision to classify this bug as an AcceptedFreezeException was made: "This bug has been noted to be a "nice-to-have" fix, so we accept it as an AcceptedFreezeException."
