Created attachment 951876 [details] lspci -vvv > lspci.txt Description of problem: Realtek on-board 8111F GBit ethernet controller is not awakened when PC resumes from S3 sleep state. The ethernet connetion remains offline, and the user has to manually click on the GUI's network manager interface and select "connect" to restore the ethernet link. The GUI mistakenly reports that the ethernet connection was last used 12 hours ago, although the sleep event took place within the past 30 minutes. Version-Release number of selected component (if applicable): F21Beta RC1 installation, KDE. Kernel and driver info listed in attachments. How reproducible: Every time PC resumes from S3 sleep state. Steps to Reproduce: 1. Install F21Beta RC1, KDE DVD installation medium 2. Configure KDE to allow suspend to S3: System Settings > Power Management > Energy Saving > Suspend Session after 30 min; Sleep. 3. Wait for Sleep state. 4. Awaken PC via keyboard 5. Ethernet connection enp2s0 remains offline Actual results: LAN adapter remains offline; has to be reconnected manually by clicking on network manager front end. Expected results: LAN adapter awakens from S3 along with PC, requiring no user intervention. Additional info: Interestingly, this problem does not occur when I use an Intel PCIe GBit ethernet card. This suggests that the r8169 driver that is used for the Realtek 8111F may be responsible for the problem. Motherboard is an ASUS M5A97LE R2.0 with the latest BIOS flash, 2501.

I forgot to mention that the ethernet adapter is also disabled on boot, and after the KDE GUI loads, the network status icon shows a disconnected state. To activate the network connection, the user has to click on the network plasmoid, click on enp2s0, and click the "Connect" button.
