Subject: [4.10][regression][PM] Oops pci_restore_msi_state() e1000e?

Hello kernel devs,

Hibernation appears broken for me in 4.10, I notice the e1000e does not resume on boot, and kernel shows why..

This kernel contains agd5f's 4.11/4.12-drm-next branches merged in.

I am unsure if this is a result of the AMDGPU performing a bad hibernation (since it hangs when it finishes dumping pages to disk and doesn't reboot system when /sys/power/disk is set for 'reboot' mode.) otherwise this bug has been persistent in 4.10-rcX.

Thanks,
Shawn
