Description:
Intel NIC devices not in /dev

Additional info:
Package Version 4.11.2-1, bug exists in both regular and -ck Linux packages

I am using a x99 chipset motherboard with a Haswell-E processor, two built-in Intel Nics and a (unused) wifi AC adapter.

Intel Nics are i218V and i211AT. Only one is being used by my host system ordinarily with dhcpd enabled on it in systemd, and the other by my virtual machine. Neither are available after booting with new kernel. I'm using a bit of an unusual configuration as I'm running a VFIO VGA passthrough VM, as described on Arch Wiki, but that shouldn't affect my network device availablility.

Steps to reproduce:
upgrade from 4.10.1-1 using pacman -Syu
reboot
no network devices are present even after modprobe e1000e... mkinitcpio doesn't seem to help either.
This task depends upon

And as a sanity check, what's the output of uname -a?

Linux vmonster 4.11.2-1-ARCH #1 SMP PREEMPT Mon May 22 06:53:49 CEST 2017 x86_64 GNU/Linux

The strange thing is, the bug has disappeared on its own. I was experiencing it earlier with the -ck upgrade to this version, now the Arch mainstream kernel had it.

Never mind, it didn't go away, I rebooted with that kernel, and the bug manifested itself again.

What devicenodes are we talking about here?
Comment by Joshua Lee (edlin) - Wednesday, 24 May 2017, 13:00 GMT
I'm not sure what device nodes... all I know is that it's acting like my NICs don't exist anymore, maybe I didn't describe what happened correctly.

What I do know is that downgrading to the earlier kernel fixes it, so the problem is with the new kernel.

Is the issue still there?
