Possible bug in iwlwifi

Hi,
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.

System: Thinkpad t430
Wifi adapter: 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)
Kernel: Linux *** 3.7.4-1-ARCH #1 SMP PREEMPT Mon Jan 21 23:05:29 CET 2013 x86_64 GNU/Linux


Steps to reproduce:
1. Suspend to ram
2. Wake the system
3. The following can be seen in dmesg:
