@Luis, too bad. currently 2.6.28.10 stable kernel updates are still in the jaunty kernel git tree. we've not upload it to proposed repo for testing. but it might be soon. Currently, latest 2.6.28-13.44 in jaunty-proposed is 2.6.28.9 stable kernel. http://kernel.ubuntu.com/~kernel-ppa/info/kernel-version-map.html @maxauthority: could you please testing our mainline kernel building on your machine and let us know the result. http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/ Thanks a lot -Bryan -- [ath9k] Kernel panic in 2.6.27-11 https://bugs.launchpad.net/bugs/319378 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This should already be part of jaunty, I made sure to inform the Ubuntu kernel team of the importance of the serialization patches. On the ath9k wiki we also keep track of known issues and the kernels when they were fixed. Let me paste the relevant section here: http://wireless.kernel.org/en/users/Drivers/ath9k Hangs with PCI devices and SMP systems This issue was due to a hardware limitation on our PCI devices whereby our device's FIFO queue got filled up and caused a loop. This issue is only present on our 11n PCI devices, its not present on our PCI-express devices nor our legacy 802.11abg devices. The fix was to serialize read/writes – a spin_lock around each read and write. This fix is not performed for PCI devices or non-SMP systems. This fix is present in 2.6.29, 2.6.28.10 and 2.6.27.22. In the future just please refer to the wiki page.

[Bug 319378] Re: [ath9k] Kernel panic in 2.6.27-11
With default ubuntu 9.04 I still had hangs, when upgrading to backport- modules (which basically is compat-wireless from end of March) they went away. Sidenote: I still had random re-/disconnects though with my card, which I just could not accept anymore, as it drove me nuts ;) (no offense, I am not paying for Ubuntu/Linux, and all devs really do great things fixing the bugs!), so i just bought another draft-n usb stick (some with a RaLink chip, rt2870sta driver), that one works great, even with N speeds which somehow i could not get with my atheros PCI card. -- [ath9k] Kernel panic in 2.6.27-11 https://bugs.launchpad.net/bugs/319378 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To get the newer stable release kernels you have no other option but to upgrade the stable kernel. Jaunty should have these updated. Keep in mind stable kernels don't automatically trickle down to the default repository on Ubunut, they first hit the proposed repository and then eventually hit the main repository. For details please read: https://wiki.ubuntu.com/KernelTeam/LinuxWireless when upgrading to backport- modules (which basically is compat-wireless from end of March) they went away. Upgrading to a stable kernel should fix it too.

[Bug 319378] Re: [ath9k] Kernel panic in 2.6.27-11
If the crash was due to ath9k and you are on an SMP system then your issue may be fixed with the latest patches I have posted which fixes this issue in wireless-testing down to 2.6.27. These patches have been posted to be merged into wireless-testing however they have not yet been merged so if you'd like to try then you'll have to apply patches yourself. Note that these patches are not yet merged into wireless- testing but will likely be so as of this week. The upstream kernel.org bug report is: http://bugzilla.kernel.org/show_bug.cgi?id=12110 The patches you can use to test: http://www.kernel.org/pub/linux/kernel/people/mcgrof/patches/ath9k/2009-03-12/serialization-v6/ As far as performance is concerned please keep in mind 802.11n aggregation support was only enabled as of 2.6.29 so you'll need at least compat-wireless for that (but the patches for serialization fix need to yet be applied on top of that). -- [ath9k] Kernel panic in 2.6.27-11 https://bugs.launchpad.net/bugs/319378 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Nearly everytime when nm-applet tries to connect with ath9k it spins its icons in the system tray for a few seconds, and then the system freezes (no mouse, etc. - need to resart). The few times where it does connect, it usually hangs itself a few minutes afterwards. Also tried today's compat-wireless drivers, same result.

We need a stack trace (oops message). Do you have that? Please try to take a picture if you cannot get it.
