I replaced Wicd with the default network manager again and now switching between networks (including eth0 -> wlan0) is possible without any freeze&reboot again. Seems like that was the combination which originally caused what I assume was a kernel panic.
Originally I had made the switch to Wicd because network manager never stored the WPA2 passphrase but that seems to have been fixed since then. Sorry for the inconvenience but maybe this will help somebody else in the future. -- System crash possibly due to wifi driver https://bugs.launchpad.net/bugs/544040 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
