Kernel return eth0 link is not ready after boot up (SL6.4 / fedora 15 etc) ...

- It occur only when BIOS/UEFI set power on by lan / pci devices
- and send a magic packet to the built-in nic mac address by e.g. ether-wake
- Dracut debug / dmesg return the link is not ready
- ethtool -s can't change the status of eth0
- eth0 is on-board Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet
- motherboard is ASRock H61M/U3S3
- modules atl1c is used for the built-in lan
- though if addr / ifconfig return information which seems normal, ethtool return speed / duplex etc unknown!
- rmmod + modprobe atl1c can't reset the eth and it is still not usable

- booting into XP make the nic works again
- rebooting into SL and the nic works again
- shut down the system and wake to boot it up into SL6 by magic packet make the nic dead again
- boot into XP make the nic works again
- disabling BIOS/UEFI power on by lan/pci devices make SL6 boot up with a working nic again !

Googling around for a numbers of day without any remedy. Help any one could help. Thanks in advance.

Hi, did you resolve this issue? i have the same problem. Except that the lan only comes up after i unplug the pc while shutdown from ac. When not doing this its not coming up in neither linux/windows/osx.
