Package: firmware-iwlwifi Version: 0.18 Severity: grave Justification: renders package unusable
Firmware iwlwifi-4965-2.ucode version 228.61.2.24 in firmware-iwlwifi 0.18 renders the wlan interface unusable. After a couple of minutes, the following message appears in syslog: iwlagn 0000:03:00.0: Microcode SW error detected. Restarting 0x82000000. .... after which no packets can be sent, though the interface appears up. Simply restarting the interface brings it up again. Downgrading to 0.17 with firmware 228.57.2.23 solves the problem for me. However, since 0.18 is already in squeeze, that version was hard to track down. I found it in lenny-backports ultimately: http://www.backports.org/debian/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_0.17~bpo50+1_all.deb Googling this problem turns up hits in every distribution imaginable. Other Debian bugs that are possibly related are 546213 and 548749. Allegedly Ubunty Karmic Koala fixes the problem, however, package linux-firmware_1.21_all.deb also contains 228.61.2.24. A combination of kernel driver and firmware version perhaps? Intel seems unaware of the problem. 228.61.2.24 is still the latest version on: http://intellinuxwireless.org/?p=iwlwifi&n=downloads This is very serious. Please revert to the older microcode version. More information about my environment: Intel Wireless WiFi 4965AGN.
