--- Comment #4 from Chris <freebsdbugs at ontoemail.com> ---
Not sure if I should reply to a closed bug. I am unable to use the network
after suspend/resume with a 12.0-RELEASE r341666 GENERIC amd64 kernel.

Suspend/resume works, except there is no network traffic. ifconfig down/up does
not restore it. There have been times where it did resume properly, but usually
does not.

dmesg:
em0: TX(0) desc avail = 1024, pidx = 0
em0: TX(0) desc avail = 1024, pidx = 0

pciconf:
em0 at pci0:0:31:6:        class=0x020000 card=0x86721043 chip=0x15b88086 rev=0x31
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Ethernet Connection (2) I219-V'
    class      = network
    subclass   = ethernet
