[opensuse-factory] wireless - iwlagn Microcode SW error
I repeatedly see "Microcode SW error detected. Restarting" in /var/log/messages when I connect to a 802.11n network. As side effect, connection speed drops to 1MBit/sec. Problem doesn't show up when connecting against 802.11ab. Hardware is Latitude E6500 with 2.6.34-9-desktop x86_64 kernel. Jun 10 08:13:40 .. iwlagn 0000:0c:00.0: Microcode SW error detected.

getting the most recent firmware from http://intellinuxwireless.org/?n=Downloads seems to have helped, maybe this cures your issue as well ?
Nope, because thats identical to /lib/firmware/iwlwifi-5000-2.ucode: jorschiedt@trinity:~/Desktop> md5sum iwlwifi-5000-ucode-8.24.2.12/iwlwifi* 10ca882a6e16e0d79e5f4b2b1b516e4e iwlwifi-5000-2.ucode jorschiedt@trinity:~/Desktop> md5sum /lib/firmware/iwlwifi-50* 4382e0ee86e57b9e5fdd1f77652da391 /lib/firmware/iwlwifi-5000-1.ucode 10ca882a6e16e0d79e5f4b2b1b516e4e /lib/firmware/iwlwifi-5000-2.ucode Only by switching off the 802.11n I got rid of the problem - but thats really not my favorite solution... jorschiedt@trinity:~/Desktop> cat /etc/modprobe.d/50-iwlagn.conf options iwlagn 11n_disable=1 amsdu_size_8K50=1 fw_restart50=1 11n_disable50=1 Cheers, Jürgen -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
