Package: network-manager
Version: 0.9.0-2
Severity: normal

Dear Maintainer,

NetworkManager periodically induces Microcode SW errors on my Intel PRO/Wireless 3945ABG card. During the system bootup:

[   48.129486] iwl3945 0000:02:00.0: firmware: requesting iwlwifi-3945-1.ucode
[   48.168070] iwl3945 0000:02:00.0: Loaded firmware iwlwifi-3945-1.ucode, which is deprecated.  Please use API v2 instead.

[   50.676844] Registered led device: iwl-phy0::TX

And then, after 20, 30, 40, 50, 60, 60, 40, 60, 100, 120, etc., seconds:

[  711.438590] iwl3945 0000:02:00.0: Microcode SW error detected. Restarting 0x82000008.

[  711.514423] Registered led device: iwl-phy0::TX

In between the messages, the wireless connection seems to be reliable. I guess something must be done to eliminate this annoying messages and following "0x82000008" restarts.

If I remove the network-manager package and load wlan0 through /etc/netowrk/interfaces, the wireless connection is stable and works silently.

Thanks for testing.

What version was the 2.6.32-trunk kernel you were using?
/var/log/dpkg.log should say.
