Re: 3.12: ethernet controller missing after resuming from suspend to RAM

[Bastien Traverse <bastien.traverse@gmail.com>]

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
