Seems this worked before 12.04?

[Fabio Marconi (fabiomarconi)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in linux.

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://help.ubuntu.com/community/ReportingBugs.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[janmartin (janmartin3-googlemail)]

It seems this is related to atl1c somehow:
http://linuxnorth.wordpress.com/2011/10/23/wireless-less/

sudo gedit /etc/modprobe.d/blacklist.conf

add the line:

blacklist atl1c

(2) Open Terminal and issue the command:

sudo update-initramfs -u

Restart Laptop is a workaround.
No more wired Ethernet anymore, but the laptop does not crash anymore too.

atl1c

[CU2 (j.holzhausen)]

Please see here:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/919815

This workaround will solve the issue. Enable Wireless and set "Boot from LAN" to first in bios.

You will get an error message when Notebook starts, but silly thing it works ;-)

Joerg

janmartin, 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? If so, could you please test for this 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 please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

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

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and 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-VERSION-NUMBER', where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream-VERSION-NUMBER', where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thank you for your understanding.

Why is this marked as expired. I'll install the new release of Ubuntu 12.10 straight after release date and then I`ll see and report on the changes.
Thanks & Regards

I have been working with this problem as well, although I ended up with a slightly different workaround. I blacklisted ath9k, ath9k_common, and ath9k_hw, and disabled wireless networking.

I tried Ubuntu 12.04 on this computer, and it was working nicely for a while, until I did a dist-upgrade a few days ago and rebooted. It would freeze a few seconds after it got to the UI prompt. It had already some wifi networks stored, that it connected to automatically.

I tried OpenSuse 12 - same thing. It froze during the installation process.

Fedora 17 would boot to the UI in a live CD, but as soon as I selected any one of the wireless networks to connect to, it would freeze.

So this is not an Ubuntu problem, per se, but it affects Ubuntu.

I blacklisted ath9k, ath9k_common, and ath9k_hw and got Fedora 17 working stably. I have the 3.3.4-5.fc17.x86_64 kernel

This weekend I installed the new release of Ubuntu 12.10 with a complete
new installation. This solved the issue for me. Everyting is working
now. No further freezes during many re-starts (warm & cold) boot.

Best regards and many thank to all the developer.
