Can you please check if your tree has following patches (Currently they are included in 4.10.2 stable) https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=154f7a1523b717cad67e0b3d2ed4c660fd1b2e7c https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=699abe249b0e2ca590284424d95490e92ccd6aeb https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=cf9d9110806493e2ea2db7d00a1a991401dfb9d5 Also can you apply following patch which addresses issue in PCI layer (This should be included in 4.10 stable branch soon ) https://www.spinics.net/lists/linux-pci/msg58742.html Thanks, Himanshu
