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.

Hi
Closing now this bugreport as later revisions of kernel with the same
firmware version seems to have solved or made the connections stable
again for reporting people. In aiming of housekeeping old bugs,
closing the report.
If proplem still persists with a recent Kernel, feel free to reopen.
Regards,
Salvatore
