Since the update of the new Fedora kernel (kernel-2.6.25.6-55.fc9.i686), the iwl4965 driver causes a kernel panic on wireless network activation (by using NetworkManager) and the system freezes completely. Version-Release number of selected component (if applicable): kernel-2.6.25.6-55.fc9.i686 How reproducible: Always Steps to Reproduce: 1. Start a wireless network by NetworkManager. Actual Results: The system became frozen by a kernel panic. Expected Results: The wireless network should have been successfully started. Additional info: Before the update of new kernel (i.e. kernel-2.6.25.4-30.fc9.i686 and before), the wireless LAN worked fine.

Does this happen every time? Are you able to use the device for any time before the crash? Can you replicate the issue with the kernels here? http://koji.fedoraproject.org/koji/buildinfo?buildID=52456

The system freezes after a wireless network is established by NetworkManager, i.e. immediately after two green lamps get turned on. Without starting a wireless network, the system seems to work fine (but it will be started automatically when I use the laptop around the wireless network registered to NetworkManager). The problem does not seem to happen with the kernel shown above. (Is this problem already fixed?)
It seems so...I think we are trying to get a new kernel through the normal release process quickly.
I'm seeing the same issue on a HP 8510w also using iwl4965. Hard freeze just after X started, which would correspond to NM bringing the network up. Started with kernel-2.6.25.6-55.fc9.x86_64 (-30 was fine) and is already fixed with kernel-2.6.25.6-57.fc9.x86_64.
The kernel-2.6.25.6-57.fc9.x86_64 has resolve the same issue on my Compaq F730US with a BCM94311MCG (b43)
