I have Acer Aspire One 722 with hw:
lspci
06:00.0 Ethernet controller: Atheros Communications AR8152 v2.0 Fast Ethernet (rev c1)
07:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
It loads module ath9k for wifi and atl1c for ethernet. There are two problems:
1) The system freezed during booting without connected ethernet network
(when system is running, it is not necessary to have a connected ethernet, also hibernation and sleeping are without problem)
2) The system freezed when is not connected ethernet and detects any wireless network

I solve it by workaround with blacklisted module atl1c (http:// forums. opensuse. org/english/ get-technical- help-here/ laptop/ 454356- acer-aspireone- 522-amd- c-50-64- bit-11- 4rc1-boot- hangs-without- ethernet- connection. html#post232496 0)
