I have had similar experiences. I suspect the culprit is the nm-applet and/or NetworkManager itself, which goes into a thread-lock.
I reported this so long ago, and yet nothing has been done about it. The issue appears only when repeatedly falling of a wireless network and reconnecting to it. And not always can one just kill nautilus. Sometimes hard reboot is necessary. -- computer freezes when sshfs blocks waiting for connection https://bugs.launchpad.net/bugs/159031 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
