I still see the issue on one of my systems, which is in fact pure Debian Squeeze updated to recent 3.10.1 kernel and firmware-iwlwifi from squeeze-backports, but this is not specific to any distribution, I think.
dmesg logs attached. System information below: # cat /etc/debian_version 6.0.7 # uname -a Linux nas 3.10.1-031001-generic #201307131550 SMP Sat Jul 13 19:59:34 UTC 2013 i686 GNU/Linux # lcpci ... 03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300 # dpkg -l | grep firmware-iwlwifi ii firmware-iwlwifi 0.36+wheezy.1~bpo60+1 Binary firmware for Intel PRO/Wireless 3945 and 802.11n cards ** Attachment added: "dmesg logs" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1099487/+attachment/3744367/+files/dmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1099487 Title: iwlwifi: Microcode SW error detected.
