Hi, I am using kde when this occurs. The workaround steps are: 1) turn of the wifi using the laptop's wifi kill switch 2) reboot 3) after logged in let kde to startup until cpu shows low usage 4) start wifi using laptop's wifi kill switch 5) from a root console : issue "ifdown wlan0" then "ifup wlan0" This may be related to kde , to high CPU usage just after kde starts and Network manager tries to connect. Anyway the driver and iwl hw must be able to recover any transient error due to high cpu or other transient causes (as KDE startup etc) when network manager tries to reconnect after RXON error. Hope this helps. Which kernel are you running? Which version of iwl5000-firmware do you have installed? Hi, I am using latest updates from standard fedora 10 yum repos. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1796 contains my logs (lspci, and debug log of iwlagn) See starting from comment #8 kernel version is latest as I update as fast as possible on this machine. I will post in a while exact output of uname -a Hope this helps . Thanks, Andrei. Hi, $ uname -a Linux tsasuhan 2.6.27.24-170.2.68.fc10.x86_64 #1 SMP Wed May 20 22:47:23 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux $ ls -la /lib/firmware/iwl* -rw-r--r-- 1 root root 149816 2008-10-21 02:42 /lib/firmware/iwlwifi-3945-1.ucode -rw-r--r-- 1 root root 149816 2008-10-21 02:42 /lib/firmware/iwlwifi-3945-2.ucode -rw-r--r-- 1 root root 149652 2007-06-20 22:30 /lib/firmware/iwlwifi-3945.ucode -rw-r--r-- 1 root root 187608 2008-07-02 23:03 /lib/firmware/iwlwifi-4965-1.ucode -rw-r--r-- 1 root root 187764 2008-12-08 22:19 /lib/firmware/iwlwifi-4965-2.ucode -rw-r--r-- 1 root root 345008 2008-06-02 19:37 /lib/firmware/iwlwifi-5000-1.ucode If there is more info that you need from the machine, please let me know. Hope this helps, Andrei. rpm -q iwl5000-firmware What is the output? Also, please try a 2.6.29-based kernel: yum --enablerepo=updates-testing update kernel Does that change the situation for you? # rpm -q iwl5000-firmware iwl5000-firmware-5.4.A.11-3.noarch I will try 2.6.29-based kernel and let you know when I have the results. Hope this helps , Andrei. Hi, upgraded kernel to # uname -a Linux tsasuhan 2.6.29.4-75.fc10.x86_64 #1 SMP Mon May 25 15:45:14 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux I am looking now to see if it still shows up. May take a while . Meanwhile just wanted to let you know there's more comments from iwlagn driver project. Hope it helps Andrei. I'm running KDE in Fedora 11 on a Dell E6500 laptop and observed something similar. It's happened twice so far, while I was watching video from hulu.com streamed to the adobe flash 10 64-bit alpha player running in Firefox 3.5beta4. -------------------------------- Jun 30 20:49:47 dell-e6500-eval kernel: iwlagn: Microcode SW error detected.

I have to quit Firefox and restart before I can continue watching video (probably not relevant, but just mentioning it for completeness).

Wifi dead. Killswitching it on/off gets the wlan back. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Why would you dig-up an old, closed bug rather than opening a new one? "Notebook frozen for a while" and "Wifi dead" do not obviously sound like the same thing to me... FWIW, "iwlagn: Microcode SW error detected" is a symptom, not a specific problem. |
