    Cool ubuntu meerkat 10.10 32-bit regression: freezes on wireless atheros ath9k

    I have been running Ubuntu 10.04 without any issue on a Compaq 311 Mini with an Atheros wireless adapter.

    From lspci:
    03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
    After upgrading (fresh install) to 10.10 I noticed my system became unstable:
    - boot process randomly freezes just before X starts
    - shutdown process hangs
    - suspend/resume freezes system, mostly on resume but also on suspend
    - sometimes random freezes when working on the netbook

    It seems the key moment where things go bad is always the point where the wireless adapter changes state. I read in various posts on the internet I am not the only one having these issues (e.g. on of the later ones: https://bugs.launchpad.net/fedora/+bug/426130) but somehow I couldn't trace anyone really working this bug.

    As I fear to end up with corrupted filesystems one day, I think this issue should be adressed.

    At this moment I installed the backport wireless modules for Meerkat:
    sudo aptitude install linux-backports-modules-compat-wireless-2.6.36-maverick-generic
    which does not solve the issue, but makes it better. My system does not freeze anymore unless I suspend it.

    To prove it uses the newer driver, a modinfo extract:
    $ modinfo ath9k

    A snippet from syslog the last time it froze because I tried to suspend it (anonymised the stuff in bold):
    Jan 11 04:00:05 dartagnan NetworkManager[1333]: <info> (wlan0): taking down device.
    Jan 11 04:00:05 dartagnan avahi-daemon[1336]: Interface wlan0.IPv6 no longer relevant for mDNS.

    Jan 11 04:00:05 dartagnan NetworkManager[1333]: <info> (18:86:AC:25:00:33): cleaning up...
    Jan 11 04:00:05 dartagnan NetworkManager[1333]: <info> (18:86:AC:25:00:33): taking down device.
    and at that point it basically died (syslog stops) and I had to do a hard reset.

    Same with kern.log:

    I am not a developer, but I can deploy a second instance of meerkat on this machine. I am willing to do any tests on this machine needed to pin down and fix this issue and work together with whoever is able to do it.

    Anyone up for this?

    Hi!

    Did you get any response?
    I seem to have a similar problem.
    I upgraded a lap top to Ubuntu 10.10 and after this it randomly freezes with no response.
    Looking at the logs it seems like it always freezes after a WLAN event and doing a IPv6 lookup (which fails because there are no IPv6 functionality in my network).

    I now have a situation where this laptop always freezes when I start Firefox so I would love if someone could help me solving this and I am glad to help debugging this.

    Try the backport wireless packages I mentioned above. If you do not suspend/resume, things should already be better.
