Hi reviewers, I suggest to backport commit "c739b17a715c net: stmmac: don't attach interface until resume finishes" to linux-5.4 stable tree. This patch fix resume issue by deferring netif_device_attach(). However, the patch cannot be cherry-pick directly on to stable-5.4. A slightly change to the origin patch is required. I'd like to provide the modification to stable-5.4 if it is needed. commit: c739b17a715c6a850477189fb7c5f9a6af74f4bb subject: net: stmmac: don't attach interface until resume finishes kernel version to apply to: Linux-5.4 Thanks.
