8086:4222 [Dell Latitude D830] iwl3945 0000:0c:00.0: Radio disabled by HW RF Kill switch

[emk2203]

After one of the latest updates, the dmesg log shows that the above error message is generated in rapid succession, regardless if the switch is activated or not. rmmod iwl3945 or shutting Wi-Fi off via menu stops the error messages.

The WLAN device is also not functional (as expected).

Does this issue go away if you boot into the previous kernel, before you applied the updates?

[Joseph Salisbury (jsalisbury)]

Also, would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I have just tested the 3.9.0 kernel-generic-030900rc3 and the problem still exists.

[QkiZ (qkiz)]

I have same problem but my wifi card can connect to hot spot. If WiFi switch is turned off while system booting wpa_supplicant hogs CPU and flood syslog with 'iwl3945 0000:03:00.0: Radio disabled by HW RF Kill switch' error.

emk2203, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, please just make a comment to this.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
