I sometimes lost the wifi-connection and I can't reconnect. Then I have to unload the ath5k kernel-module and suspend my laptop. Then I resume the session and load the ath5k. Then I can connect to the wifi-network. But often this connection get lost after a short time.
I tested it with mainline kernel v3.4-rc3-precise.
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc3-precise/
No "ath5k phy0: gain calibration timeout" message with this kernel version.

Sebastian Schlatow, 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/KernelMainl ineBuilds . 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.
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' .
Please let us know your results. Thanks in advance.
