Got some problems with iwl3945 wireless driver on a Lenovo Thinkpad Z61m. Connection drops, kernel log fills up with "No space for Tx" & friends, and the only way to get re-connected is to disable/enable wireless network (I do that through NetworkManager, kill switch works as well). There is no kernel crash, though. Problem seems to be more easily triggered with certain network traffic patterns like streaming video. linux-image-2.6.32-21-generic [2.6.32-21.32].
