john, this looks like b43 is corrupting memory to me.  a use after free perhaps?
Comment 4 John W. Linville 2008-03-04 13:49:54 EST
Michael, for reference this kernel corresponds to the top of the 
current "pending" branch in wireless-testing, as well as all the current fixes 
sent to 2.6.25.  Have you seen anything similar reported?
Comment 5 John W. Linville 2008-03-04 13:53:57 EST
Gerald, what was the last working kernel for you?
Comment 6 Michael Buesch 2008-03-04 14:00:10 EST
Didn't see that before, but to me it looks more like a mac80211 bug or memory
Comment 7 Gerald Cox 2008-03-04 14:10:23 EST
I backed out to:

and it is working fine with no error message or lockup so far.  I also didn't
have the problem with any of the other F9 Alpha kernels.

I receive the error message with the git4 kernel about 1 or two minutes after
boot.  Lockup then varies depending on what I am doing.  I have to poweroff to
Comment 8 Michael Buesch 2008-03-04 14:16:19 EST
see #435962
Comment 9 John W. Linville 2008-03-05 13:05:52 EST
Gerald, please try kernel-2.6.25-0.90.rc3.git5.fc9.  It has a patch that cured 
a similar problem in yesterday's F8 kernels.


Does that resolve things for you?
Comment 10 Gerald Cox 2008-03-05 16:50:45 EST

kernel-2.6.25-0.90.rc3.git5.fc9 appears to have resolved the problem.  The only
thing I noticed was I needed to re-enter my WPA key after the first boot.  After
that, the settings were saved.  Thank you.
