Removing"quiet" from the kernel command line workaround that problem. I'm going to see if I cant gather some useful info on why that's happening and file it in a separate report
F18 version of well known bug.

This is Fedora top problem currently according to https://retrace.fedoraproject.org/faf/problems/hot/*/*/kernel/ This issue (or actually a few issues which manifest itself by this warning) should be fixed in 3.8. Not sure when fedora 18 (and fedora 17) will update to 3.8 kernel, perhaps would be good to backport driver from 3.8 to 3.7 kernel?

F18/F17 will pick up 3.8 right around the 3.8.1 timeframe, so most likely within the next few weeks. We had discussed doing a backport, but figured we would just wait. If a backport patchset showed up, we'd probably take it though :)
in the meantime, the warning has been removed in the latest update, so we'll not see further reports of this at least.
Appeared after first log in after boot... No action on my part. Package: kernel OS Release: Fedora release 18 (Spherical Cow)
after upgrade Package: kernel OS Release: Fedora release 18 (Spherical Cow)
This should be fixed in the 3.8 updates. If you see new brcmsmac bugs, please file separate ones, as they won't be related to this due to the code being completely different.
