Did you do a git > bisect. Tinywrkb confirmed to me in private communication that revert of 5502b218e001 fixes Ethernet for him on effected system. He also referred me to an old Cubox-i spec that lists 10/100 Ethernet only for i.MX6 Solo/DualLite variants of Cubox-i. It turns out that there was a plan to use a different 10/100 PHY for Solo/DualLite SOMs. This plan never materialized. All SolidRun i.MX6 SOMs use the same AR8035 PHY that supports 1Gb. Commit 5502b218e001 might be triggering a hardware issue on the affected Cubox-i. I could not reproduce the issue here with Cubox-i and a Dual SOM variant running v5.3-rc8. I have no Solo/DualLite variant handy at the moment. baruch -- http://baruch.siach.name/blog/ ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - baruch@tkos.co.il - tel: +972.52.368.4656, http://www.tkos.co.il - _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
