8086:4222 WiFi (Intel 3945ABG) does not work on Sony Vaio (VGN-FZ31SR) with Ubuntu 12.04

[Vladimir Kondratyev]

1) I have working WiFi with Ubuntu 11.10. The default installation. The hardware configuration is Sony Vaio notebook (model VGN-FZ31SR) with Intel 3945ABG WiFi adapter on board.

2) I have _VERY_ strange problem when I'm booting from USB-flash drive (Ubuntu 12.04 32-bit desktop edition). First of all the WiFi is not working and the output of "dmesg | grep iwl" command is:

3) When I boot again from hard-drive to old installed Ubuntu 11.10, the WiFi is not working any more. I can restart the laptop any number of times and WiFi is not working. The output of "dmesg" is very similar:

[ 14.041145] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s
[ 14.041149] iwl3945: Copyright(c) 2003-2011 Intel Corporation

[ 14.174969] iwl3945: probe of 0000:06:00.0 failed with error -2

4) The only way to get working WiFi is to go to BIOS and perform "load default settings". I want to admit that BIOS settings are all default and visually nothing changes. After that I can run Ubuntu 11.10. Here is the output of "dmesg"

[ 13.703718] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s
[ 13.703722] iwl3945: Copyright(c) 2003-2011 Intel Corporation

[ 13.703844] iwl3945 0000:06:00.0: setting latency timer to 64
[ 13.758904] iwl3945 0000:06:00.0: Tunable channels: 13 802.11bg, 23 802.11a channels

[ 15.229584] iwl3945 0000:06:00.0: loaded firmware version 15.32.2.9

The problem is 100% reproducible. So every time I boot into Ubuntu 12.04, I got persistently non-working WiFi.

I'm ready to provide any further information, because I want to upgrade to new Ubuntu version.

I've booted into Ubuntu 12.04 (use wired connection to LAN) and performed "apport-collect 1018116" command. If you need any other information, please ask.

[Vladimir Kondratyev (vladimirkondratyev)]

I installed latest kernel upgrade for Ubuntu 11.10 (kernel 3.0.0-22-generic) and I have the _same_ WiFi problem an in Ubuntu 12.04. WiFi works only in kernel 3.0.0-17-generic which was installed before.

[penalvch (penalvch)]

Vladimir Kondratyev, thank you for reporting this and helping make Ubuntu better. If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

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', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

[Vladimir Kondratyev (vladimirkondratyev)]

I'll test upstream kernel as soon I am back from vacation :)

Please note, that some regression was done in Ubuntu 11.10 kernel. WiFi works in kernel 3.0.0-17-generic and does not work in 3.0.0-23-generic. So this bug is not about Ubuntu 12.04 only. Ubuntu 11.10 is affected either.

[Vladimir Kondratyev (vladimirkondratyev)]

I've just installed upstream kernel. The "uname -a" reports "3.2.27-030227-generic #201208101235". WiFi works! As far as I understand, this is a kernel from Ubuntu 12.04, but it works in Ubuntu 11.10

I also tested kernel "linux-headers-3.0.0-24-generic" and WiFi also works.

[Vladimir Kondratyev (vladimirkondratyev)]

Christopher, I've installed Ubuntu 12.04.1 and WiFi still does not work. To get working WiFi I need to go into BIOS every time before I boot and perform"Load default settings". After that Ubuntu starts and WiFi works. Otherwise, WiFi does not work and Ubuntu does not see WiFi hardware.

[Vladimir Kondratyev (vladimirkondratyev)]

I'm not a kernel hacker, but I performed some research in Google, and found that there are many people complains about iwl3945 module and "mac is in deep sleep" error.

Please take a look at http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2143
Perhaps it's related to power management in kernel.

[penalvch (penalvch)]

Vladimir Kondratyev, 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, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5

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.
