I have the same motherboard as the OP and an Nvidia graphics card with the proprietary driver.
I didn't experience the problem after upgrading Kubuntu from 13.04 to 13.10 with 3.11.0-12. After upgrading to 3.11.0-13 a few days ago, though, I have had the problem intermittently. Testing my system a few times with 3.11.0-13, it was fine, but I've had the problem twice with the system slept overnight. I'm currently back on 3.11.0-12 without a problem. In my case, the system wakes up and I can enter a few characters of my password into LightDM. Then the system freezes. It's unresponsive to the keyboard and mouse, and pinging it from another machine fails. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241582 Title: [Asus M4A88TD-V EVO/USB3] System freezes after suspend to RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
