Bug Description

I had this Problem before in the 2.6.23-22 Kernel. It was fixed in the 2.6.23-23 Kernel. But when I upgraded to the new 2.6.23-24 kernel this problem appeared again.
The Problem is:
When I run the Laptop in battery mode, the Atheros AR5007EG does not work. I cannot connect to any wireless network (No Networks found) and the CPU Usage of "phy0" is 100% for 5 seconds or so. This repeats every 60 seconds or so. The kernel says:
[ 4965.826400] __ratelimit: 4 callbacks suppressed
[ 4965.826411] ath5k phy0: gain calibration timeout (2412MHz)
[ 4966.214049] ath5k phy0: gain calibration timeout (2417MHz)

Happend to me as well on 2.6.32-25-generic Ubuntu 10.04. Although I could not reproduce this, it happened when i booted up on battery and plugged power just before logging into gnome. No wireless networks available and process phy0 firing around every minute and taking up all processor time, it almost freeze up system, making it unusable. My specs: AMD Turion x2 1.8Ghz, nvidia 7000M, 3GB RAM, Atheros AR5001 Wireless Adapter.

I'm also having this exact issue, I had it back in beta of 10.04 so I reverted to 9.10, and how i'm having it again. It seems to be affected by temperature, if I have my laptop on my bed or lap it seems to drop faster. If on the desk it has been known to last over night.
Here is a dmesg I took just after the wifi dropped earlier: http://pastie.org/1188738

As the author stated, it's impossible to maintain productivity with such an unreliable connection and is a real inconvenience, but I really like the native iPhone support in 10.04 so would like to try get it fixed.

Thanks,

Martin

This really sucks and I cannot work with my laptop without a lan cable and the CPU usage of 100% sucks!

I have the same problem on the Toshiba Satellite A215-S4697.
2.6.32-25-generic kernel, x86_64 build, Ubuntu 10.04
This happened immediately after updating the kernel with Update Manager.

Small differences:
1. Although the problem does start when I work on battery, occasionally the problem will also occur while on AC power.
2. Along with this error, the TTY terminals also spam "ath5k phy0: noise floor calibration timeout," alternating between the errors.
3. The problem once didn't occur while on battery, but I have yet to re-create it.

I am having the same problem: Hardware AR5007EG (lspci says AR5001), Asus F3Ke laptop. It sometimes connects, and sometimes doesn't.
Was still good with the 2.6.31-rt kernel which was available in 10.04, but not anymore in 10.10.
The interesting thing is that lshw is always the same when it is bad, and always the same when it is good. I will attach my lspci, lshw-good and lshw-bad and the difference between the lshw's.

Small update on my situation: I connected via wifi and worked a bit on my laptop. Then i was asked to check some newly mounted rj-45 plugs, so i disconnected from wifi and connected to internet via rj-45 cable a few times. When i wanted to go back to using wifi, NetworkManager showed no wifi available, same goes for iwlist scan fired from root terminal. There was no high la, or high processor use, but saw this in my syslog:

Guys,

Same here, although in my case things happen somewhat diffent. I have a rock solid connection, no problems at all, except when I do a suspend/resume cycle. Very often, when my machine returns, I can't connect to my router and I experiment all of the simptoms already noted here, same messages and all. Another difference is that I can't get the wireless back by simply rebooting - I need a hard boot (power off/on) to get the thing working again.

My machine is an AMD-based laptop - lspci attached. Using 10.10 amd64, fresh install. Something else I can help, please let me know.

Started happening today with a Natty (11.04) update from kernel 2.6.37-12.26 to 2.6.38-1.27.
This is a regression since going back to the previous kernel fixes the problem.
System mostly unusable due to very high spikes every few seconds.

I will give you some further information about this issue.
This bug seems to affect the powernow-k8 driver in the Ubuntu Versions from 9.10 until 11.04
If I rember correctly Ubuntu 9.04 powernow-k8 was working.
This issue seems to have two main characteristics:

1) Most Atheros WLAN-Adapters stop working with "gain calibration timeout" at dmesg
2) Frequency-Scaling on AMD-Processors stops working at battery-mode -> Its stuck at the lowest frequency

This Bug is reproducable if one boots up with ac device plugged in and plugs off the ac-device.
-> After a short time wlan adaptor stops working and dmesg gives "gain calibration timeout" messages.
The other way round, boot up on battery , plug in ac-device the same bug occures.

There are some "workarounds"

1) The easiest thing is to power down the computer, remove the battery an power up again (Bug occures again from time to time)
2) Another Option is to disable powernow in Bios Settings. (No more WLAN-Bugs, but Frequency-Scaling is not working at battery and ac-mode)
3) Experimental: Some people have managed to get rid of this Bug by using the phc-k8 driver instead of powernow-k8
   There is a Ubuntu ppa for this driver att linux-phc.org The driver is mainly used for undervolting modifications.
   Look at https://bugs.archlinux.org/task/18982

Here is another workaround that has been working for me for the past 2 days.

Before suspend unload the ath5k module and reload on resume.
$ sudo modprobe -r ath5k
..hit suspend button..
..come back from suspend..
$ sudo modprobe ath5k

Probably these commands can be put into a script somewhere so they happen automatically but I don't know where that is.

So this is the way to solve it with linux-phc Kernel:

First add ppa for linux-phc Kernel:
sudo add-apt-repository ppa:linux-phc/ppa

Update the Repositories:
sudo apt-get update

No install the headers an the kernel itself
sudo apt-get install linux-headers-generic-phc
sudo apt-get install linux-generic-phc

Reboot your System with the phc-kernel (usualy the first entry in grub)
No you need to install the patched modules for your System

Download patched modules for AMD
http://www.linux-phc.org/forum/download/file.php?id=83

or INTEL
http://www.linux-phc.org/forum/download/file.php?id=94

unpack them eg to your home directory Before we can install them we need to do some bugfix.
The utsrelease-header-file is missing on this kernel so we create it by hand
sudo nano /usr/src/linux-headers-<your-version>-generic-phc/include/linux/utsrelease.h
where linux-header-<your-version>-generic-phc has to be your installed version eg linux-headers-2.6.35-28-generic-phc
insert into this file: #define UTS_RELEASE "2.6.35.28+drm33.5" (your version of course)
and no install the modules
sudo make dmks_install
Reboot again and hopefully no more gain calibration timeout

I have this issue with the kernel 2.6.38-8-generic
The problem is observed when waking up from suspend to RAM (stand-by) mode.

I've had frequent "gain calibration timeout" messages and cpu frequency mismanagement (I thought so)..

the problem seems to be easier after I removed a carpet of dust from the ventilation output :)

i.e. "gain calibration timeout" after that happened just once (in ~3 days), and cpu frequency scaling works like expected.

I think (at least from my observations) that these messages (both "gain calibration timeout" and "noise floor calibration timeout" appear when the electricity goes off. I do not know how this differs from simply plugging the power cord off, but plugging off does not reproduce the problem. Maybe the wireless AP also has to be plugged off in the same moment for thus error to occur.

Jan, thank you for reporting this and helping make Ubuntu better. 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

Also, if you could 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. Please let us know your results.

Thanks in advance.

I am soory, I posted it too early, the bug is still there. :( I think it has something to do with the heat, when the Laptop becomes too hot and it runs on battery mode(which is kind of buggy, too), the WLAN Module ath5k stops working and this error comes up.

Sounds like 3.4 kernel fixes this issue indeed. Any chance of 3.4 kernel being officialy backported into Ubuntu 12.04 LTS or maybe 12.04.1 ships with kernel 3.4 as standard?
