While it looks as a duplicate of Bug 495223 = Bug 495003 those bugs should have been already fixed (kernel-2.6.29.1-64.bz495003.2.fc11) in my kernel version. Version-Release number of selected component (if applicable): kernel-2.6.29.2-126.fc11.x86_64 How reproducible: Each time my network setup crashed (~5 times). The artificial reproducer below was tried once on a "s" (init s) GRUB boot. Steps to Reproduce: modprobe iwl3945 ifconfig wlan0 up rmmod iwl3945 Actual results: Crash. Seen some (cut as too big) oops on the screen. No local other machine and kdump just hangs (nothing dumped). Expected results: No crash. Additional info: Easy workaround is to do before rmmod: ifconfig wlan0 down Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/345710/comments/9 ------------------------------------------------------------------------ On 2009-05-08T13:01:36+00:00 John wrote: I confirm that my iwl3945 machine crashes on rmmod when the device is up. Please try to capture an oops, as will I.

Fix: Two patches from upstream, the first moving the call that restarts the workqueue on the way down to be executed before stopping the workqueue. The second patch makes the call stopping the workqueue wait for any running worker. Testcase: Removing and loading the module in a loop (has been verified to be working after the patches being applied). --- I can reliably reproduce a total system lock-up (no response to SysReq keys) when-ever the module is removed. It occurs about 3 seconds after the removal has completed whilst the notification of removal is still on-screen. sudo modprobe -r iwl3945 sudo modprobe iwl3945 uname -a Linux hephaestion 2.6.28-11-generic #35-Ubuntu SMP Wed Mar 18 21:55:34 UTC 2009 x86_64 GNU/Linux lspci -nn | grep -i Wireless 06:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02) Because the lock-up is total the log files aren't synced and therefore the last 5 seconds or so of messages are not in the logs to help diagnose it. Tomorrow I shall use a netconsole connection to try to get more information.
