Comment 10 for bug 324921

I haven't tried the rmmod suggestion yet. Will do that later.

After installing the new -14 kernel built by Stefan for https://bugs.launchpad.net/bugs/355057 my madwifi stopped working again. The log entries look exactly the same as the last time. I guess rebuilding and reinstalling it will help again, but I haven't done it so far, just in case somebody is interested in further details (and it's too late for me anyway).

I guess after the upgrade it starts to use the default Ubuntu driver, but I don't see any explanation why. This time ath_pci is not commented out in /etc/modules.

Here are some kernel log lines:
