2. Logged in normally
3. ABRT popped up advising me of kernel crash (OOPS)

This problem is fixed in 2.6.37 kernel and newer, we will not backport fixes. You may consider update to F-15, or use http://people.redhat.com/sgruszka/compat_wireless.html if problem annoys you.
Comment 3 Scott Marshall 2011-10-03 20:23:29 UTC 
Unfortunately, Fedora 15 is an absolute festering pile of excrement thanks to the lamentably useless Gnome v3.

Given how woeful Fedora 15 is, I hope & pray that Fedora 14 will remain supported until at least Fedora 17, because I reckon it will be that long before a viable replacement for F14 will actually by available.

Yes, I've tried F15, and it is unusable, as the desktop paradigm has changed too much, too fast and too soon.

Telling me that you won't backport fixes to an active release of Fedora, that is still listed as FULLY SUPPORTED, is NOT acceptable.

It won't.  It will be EOL'd one month after F16 is released.

There are other desktop environments available.

We do not fix that because simple fix for that problem does not exist. This warning is triggered because of various bugs (race condtions) in iwlwifi and mac80211 scanning code. To fix that, we had to massively rewrite that code. This is nothing that could be easily backported to older kernel.

To helps with such case, we allow to use newer wireless drivers via compat-wireless package. I just realized that packages from my page do not work on F-14 due to vmalloc symbol conflict. I'm going to fix that (fix should be ready this week).
