Bug#550534: firmware-iwlwifi: iwlagn 0000:03:00.0: Microcode SW error detected., Restarting 0x82000000.
Hi everyone,
I have the same problems, too. Debian squeeze runs on a Lenovo R61 with
the following WLAN-NIC:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or
AGN [Kedron] Network Connection (rev 61)
uname -a
Linux NBOOK 2.6.30-2-686 #1 SMP Fri Dec 4 00:53:20 UTC 2009 i686 GNU/Linux
iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"tztztz"
Mode:Managed Frequency:2.462 GHz Access Point: xyzyzy
Bit Rate=54 Mb/s Tx-Power=15 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Encryption key:blablabla
Power Management:off
Link Quality=70/70 Signal level=-27 dBm Noise level=-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
The WLAN-connection is secured with WPA-PSK.
Before a new installation with squeeze I have used Debian stable with
the default packages of the stable-branch. (firmware-iwlwifi-0.14). This
installation runs daily without any problems about one year. About that
past 12 months I have never lost the WLAN-connection.
But after I have made a complete new installation with a
squeeze-installation-CD the problem occurs. The problem couldn' t be
reconstruct for example with more sessions at the same time or full
bandwith downloads. Sending a kind of keep-alive by a ping to my
access-point in a cronjob every minute doesn't fix the problem.
I have made a "downgrade" and a "upgrade" to firmware-iwlwifi-0.14
(lenny) or firmware-iwlwifi-017 (0.17~bpo50+1_all) and
firmware-iwlwifi-0.22 (sid) but unfortunately without any positive
improvements.
I think its rather a combination with and the firmware-iwlwifi (0.18)
linux-image-2.6.30-2-686 (6.30-8squeeze1) packages.
Greetings
