Trying what Tim said:
Previous behavior:
On 2.6.24-19 kernel, with linux-backports-modules-2.6.24-19 installed:
sudo modprobe -r iwl3945 --> The module is correctly unloaded
sudo modprobe iwl3945 --> The module is correctly loaded
On 2.6.24-20 kernel, with linux-backports-modules-2.6.24-20 installed:
sudo modprobe -r iwl3945 --> kernel panic (I have an Intel 3945 wifi chipset)
--- I uninstalled linux-backports-modules-2.6.24-20 and rebooted ---
New behavior:
On 2.6.24-19 kernel, with linux-backports-modules-2.6.24-19 installed :
sudo modprobe -r iwl3945 --> The module is correctly unloaded
sudo modprobe iwl3945 --> The module is correctly loaded
On 2.6.24-20 kernel, with linux-backports-modules-2.6.24-20 NOT installed :
sudo modprobe -r iwl3945 --> The module is correctly unloaded
sudo modprobe iwl3945 --> The module is correctly loaded
So this bug is definitely related to the Intel WiFi driver that is in
the linux-backports-modules-2.6.24-20
** Changed in: linux-backports-modules-2.6.24 (Ubuntu)
Status: New => Confirmed
** Summary changed:
- linux-image-2.6.24-20-generic causes kernel panic upon suspend
+ linux-backports-modules-2.6.24-20-generic causes kernel panic when unloading
Intel Wireless driver
** Description changed:
- Binary package hint: linux-image-2.6.24-20-generic
+ Having an Intel 3945ABG WiFi chipset :
- Ubuntu 8.0.4.1
+ Actual behavior:
- attempting to suspend to RAM causes kernel panic
- see attached output of lshw
+ On 2.6.24-19 kernel, with linux-backports-modules-2.6.24-19 installed:
+ sudo modprobe -r iwl3945 --> The module is correctly unloaded
+ sudo modprobe iwl3945 --> The module is correctly loaded
+
+ On 2.6.24-20 kernel, with linux-backports-modules-2.6.24-20 installed:
+ sudo modprobe -r iwl3945 --> kernel panic (I have an Intel 3945 wifi chipset)
+
+ --- I uninstalled linux-backports-modules-2.6.24-20 and rebooted ---
+
+ New behavior:
+
+ On 2.6.24-19 kernel, with linux-backports-modules-2.6.24-19 installed :
+ sudo modprobe -r iwl3945 --> The module is correctly unloaded
+ sudo modprobe iwl3945 --> The module is correctly loaded
+
+ On 2.6.24-20 kernel, with linux-backports-modules-2.6.24-20 NOT installed :
+ sudo modprobe -r iwl3945 --> The module is correctly unloaded
+ sudo modprobe iwl3945 --> The module is correctly loaded
+
+
+ Same thing with iwl4965 for people who have an Intel 4965AGN WiFi chipset.
+
+ This bug occurs every time the driver is unloaded, including suspending
+ to RAM, but not while shutting down completely the system.
