Description David Duncan 2010-10-01 00:24:33 UTC 
Unable to init Intel wireless network controller 3945ABG at boot.  Issue is intermittent.  Card reports: 
iwl3945 0000:0b:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF

Issue occurs on 2.6.34.7-56.fc13.i686 and 2.6.34.7-56.fc13.i686.  
Issue does not occur on 2.6.34.6-47.fc13.i686 or earlier.  

iwl3945-firmware-15.32.2.9-4.fc13.noarch

Laptop is a Dell XPS M1530 with BIOS revision A12.  

Steps to Reproduce:
1.  Boot one of the two afflicted kernels.  I assume that only the most recent is appropriate.    
  
Wireless LAN is not accessible.

dmesg | grep iwl from system with successful initialization of the iwl3945 on latest F13 kernel

dmesg from 2.6.34.7-56  shows this working now.  

I modified the bios settings for the wi-fi locator from dynamic to basic.  This seems to have brought the card out of the "deep sleep".
Comment 4 David Duncan 2010-10-19 18:13:32 UTC 
Since the wireless is functioning and we are so close to F14, I am going to close this and consider it working for me.  If it appears again after I upgrade, I will follow up.
