> I might have stumbled upon a bug in iwlwifi - it doesn't work after resuming from suspend to ram. The curious thing is that this only happens when suspending with AC power connected. Id doesn't happen when suspending on battery only. Below are some system specs and repro steps. Please let me know if you need more information.
