Comment 191 for bug 276990

@Winckler: I've had some kernel panics while connected to a non-11n network as well. So I assume it's nothing to do with this 11n bug and I've opened a new bug for the panics, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/348731, so perhaps you could add something about your system config there. There are also some suggestions on how to capture kernel output about the panic (not that easy since the whole system locks up).
