Version-Release number of selected component (if applicable): last working : iwl3945-firmware-2.14.1.5-2 kernel-2.6.23.1-49.fc8 i tried any kernel after this level and all fail, even kernels from kojo .. the latest i tested is kernel-2.6.23.9-80.fc8 still the same errors .. How reproducible: install any kernel after kernel-2.6.23.1-49.fc8 on 64 bit Laptop and try to connect to a network Steps to Reproduce: 1. boot up 2. iwlist wlan0 scan 3. iwconfig ... Actual results: system freezes for a short time (3-4 sec) then continues .. but no network connected Expected results: i should get an ip from my network ..

Are you using the disable_hw_scan=1 option for the iwl3945? I was, and I started getting the same error on my T60 with kernels after 2.6.23.1-49.fc8 After removing the disable_hw_scan=1 option, the error has gone away, and I'm connecting error free with kernel-2.6.23.9-85.fc8.
Reassigning to the kernel since I doubt this is firmware package related... Sven : Can you please confirm if this problem persists, or if an F-8 update has fixed it since?
i updated to the latest fc9 kernel from kojo , that fixed my problem ..
[18192.609271] iwl3945 0000:03:00.0: Microcode SW error detected. Restarting 0x82000008. This happens on my F15 machine (lenovo x60) with kernel 2.6.38.2-9.fc15.i686 it can connect and works fine, but those errors appear on dmesg every few minutes (110 times since 16:40:59 until 20:18.58)

this problem recurs in Fedora 15 and may be a regression, but this ticket is closed so I opened a new bug #699447 for this.
