Description of problem:
With the lastest kernels iwl3945 does not cause problems if it is just loaded,
but if there's an active (wpa2 in my case) link the system can not suspend or
shutdown properly. I tried removing the module from /etc/pm/scripts without
success. At shutdown if there was a wireless connection the kernel hangs while
trying to sync the hard disk cache (one of the last messages before powering off
the laptop).

Version-Release number of selected component (if applicable):
vmlinuz-2.6.21-1.3144.fc7 to vmlinuz-2.6.21-1.3149.fc7

How reproducible:
Every time

Steps to Reproduce:
1. Install F7t4
2. Update
3. Connect to a wireless AP
  
Actual results:
Can't suspend (disk/ram) or shutdown normaly.
