@Simon - Thanks for clarifying! Now everything works. To sum up: (1) When using 12.04, my ethernet wasn't working (I have Atheros AR9485 wireless and AR8162 wired), so I installed linux-backports-modules- cw-3.4-precise-generic and switched to alx. All was well.
(2) Later on, I updated to 12.10 (linux kernel 3.5). I had the problem that suspending only worked the first time after each reboot. (3) I removed the package linux-backports-modules- cw-3.4-3.2.0-40-generic in ubuntu software center. In theory, doing this should have made no difference whatsoever to my computer (according to Simon). But, for some mysterious reason it fixed my suspend problem. (Or else the problem went away by coincidence at the same time.) I still had the problem that the network manager cannot reconnect the wired connection after a suspend. (4) I installed linux-backports-modules-cw-3.6-quantal-generic in ubuntu software center. I restarted (twice), and now everything works perfectly. :-D -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1130037 Title: regression-update kernel 3.5.0-24 alx suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1130037/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
