Description of problem: problem found when fedora 16 power management testday when tried suspend and hibernate testcases it caused freeze of machine smolt profile of machine - HP nx6125: http://www.smolts.org/client/show/pub_a5686524-3975-4025-86bc-a3b5e45365a8 machine was suspended, and then try to resume, it works, but after few seconds it freeze at all.

Basically what seems to happen here is that on resume the driver goes to load the firmware and the helper isn't enabled yet. Larry Finger has been working on this for various drivers: http://thread.gmane.org/gmane.linux.kernel.wireless.general/84615 http://thread.gmane.org/gmane.linux.kernel.wireless.general/85406/focus=85462 (Adding Larry to CC just for awareness since b43 was one of the drivers)
Created attachment 566430 [details] Test patch for driver b43 to implement asynchronous firmware loading Please test this patch. It has been tested on my system, but my system does not suspend. As a result, I cannot check for your problem.
(At first, I thought Josh say "just for awesomeness"!) Test kernels with the patch from comment 2 are building here: http://koji.fedoraproject.org/koji/taskinfo?taskID=3840252 Please give them a try and post the results here...thanks!
[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.
[Mass hibernate bug update] Dave Airlied has found an issue causing some corruption in the i915 fbdev after a resume from hibernate. I have included his patch in this scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=3940545 This will probably not solve all of the issues being tracked at the moment, but it is worth testing when the build completes. If this seems to clear up the issues you see with hibernate, please report your results in the bug.
