SubjectRe: 3.12: ethernet controller missing after resuming from suspend to RAM
Hello,

I'm encountering the exact same problem (same model of machine, same
controller, same OS) and was wondering where this bug was at.

I just used my Ethernet NIC for the first time on an up-to-date
Archlinux; it was working fine until I suspended to RAM: on resume the
Realtek/Ethernet device had completely disappeared.

The two entries absent from lspci output after resume are:
$ sudo lspci -v

Trying to modprobe r8169 & rtsx_pci didn't change anything.

Tell me whether my dmesg may be of any use, but I doubt it as it is
pretty close to original poster's one.

Thanks,
Bastien
