Another Way to fix ist: add processor.ignore_ppc=1 to grub boot parameters -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/610440 Title: ath5k phy0: gain calibration timeout after Kernel Upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 610440] Re: ath5k phy0: gain calibration timeout after Kernel Upgrade
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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/610440 Title: ath5k phy0: gain calibration timeout after Kernel Upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have the same problem on my MSI laptop, with Ubuntu 10.10 x64 vendor_id : AuthenticAMD cpu family : 15 model : 104 model name : AMD Turion(tm) 64 X2 Mobile Technology TL-60 Frequency Scaling not working -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/706089 Title: Frequency scaling doesn't work in current kernels -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 610440] Re: ath5k phy0: gain calibration timeout after Kernel Upgrade
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.
