Test Environment =============================================== Platform : Intel SDV M3M31/M3X15/M3M41 Wireless Card : Intel(R) WiFi Link 4965/3945/5100/5300 OS : Redhat Fedora release 10 (Cambridge) 32/64bit AP : Cisco 1250 uCode : iwlwifi-4965-2.ucode 228.57.2.23 iwlwifi-3945-2.ucode 15.28.2.8 iwlwifi-5000-1.ucode 5.4.1.16 Source : commit bc51dd744dc3ce75c4aab96681d6bfa322cb184e 2.6.29-rc3 (3945 card) issues: when set txpower off/on, log has Error message. As we know it is expected message. But in view of users, Error in dmesg will *confuse them*. suggest closing relevant order and don't send that signal to show error message. Steps to Reproduce: 1. reload driver 2. ifconfig wlan0 up 3. iwconfig wlan0 channel <CHAN> essid <ESSID> 4. ifconfig wlan0 <IP_ADDR> 5. ping <IP_SERVER> 6. iwconfig wlan0 txpower off 7. sleep 20 8. iwconfig wlan0 txpower on---->Error in dmesg is below: iwlagn 0000:03:00.0: Error sending REPLY_ADD_STA: enqueue_hcmd failed: -5 iwlagn 0000:02:00.0: Error sending REPLY_ADD_STA: time out after 500ms. iwl3945: Error sending REPLY_LEDS_CMD: iwl3945_enqueue_hcmd failed: -5 iwl3945: Error sending REPLY_TX_PWR_TABLE_CMD: iwl3945_enqueue_hcmd failed: -5 iwl3945: Error sending REPLY_LEDS_CMD: iwl3945_enqueue_hcmd failed: -5

Are you still getting errors for REPLY_ADD_STA. I think for txpower off you should get the error for REPLY_LEDS_CMD only which is actually fine because of SW rfkill. If you are getting error only for LEDS then pease close this bug.

Yeah, Only REPLY_LEDS_CMD is always printed on 3945 card. It might not be a issue, so we set the severity enhancement. Could you tune it and make error disappear in log even though "SW rfkill"?
Created an attachment (id=2007) [details] Patch to try
I have created one patch for you.But this is not the right thing to do. I don't think we will see this in upstream.
One more reason it will only show in 3945 is that we have leds command for 3945 while rest of the chips have register setting. And this is expected behavior for 3945.
I retest it on 5100 and n-band, after switching txpower, dmesg prints "Error sending REPLY_ADD_STA" and "HW problem - can not stop rx aggregation for tid 0".

With the new rfkill system we should not be asked to do work when rfkill is enabled. This should thus be fixed now.
Yes. I didn't see it anymore.
