In my setup there are 2 things that cause the unregister_netdevice error: pccardctl eject and the module unload of all networking modules. Unloading the rt2500pci driver leads to trouble. So I whitelisted the rt2500pci, rt2x00pci and rt2x00lib modules. I further changed the pccardctl eject/insert combo in the suspend.d/resume.d with pccardctl suspend/resume. This leads to reliable suspend/resume for me, without further killing of processes.
Networkmanager doesn't have a working net connection at resume however, but just selecting my ap again in the applet will cause a good reconnect. This is good enough for me (for now, it's 2.35 AM here...). Maybe I'll look into the lost net connection after resume some more later. -- [gutsy] NetworkManager causes hang when suspending https://bugs.launchpad.net/bugs/137666 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
