Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[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.

[Jost Menke (jmenke)]

The upstream kernels are only available fo x86 /x86_64. The Powermac G5 is equipped with a 64 bit PowerPC CPU.

Jost,
this looks like a duplicate of bug 950295 - please test the latest kernel from precise-updates (3.2.0-25.40) and see if this issue persists.

[Scott Miller (samiller25)]

I am experiencing the exact same bug, running on an iMac G5 PPC as well. I am running the 3.2.0-25.40 kernel, and as far as I know I have all updates from precise-updates.

How is this a duplicate of 950295? The kernel does not hang in this case; I simply do not get a working wireless network.

Jost Menke, 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, as a potential WORKAROUND, could you please report the results following https://help.ubuntu.com/community/BroadcomSTA%28Wireless%29 ?
As well, 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>

Offline apport steps may be found at https://help.ubuntu.com/community/ReportingBugs#Filing_bugs_when_off-line .

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

This issue should be fixed by the mainline Linux kernel commit 4c374af5fdee4bc6b4f5ea96c1a0f0ad7d3566be (powerpc/dma-iommu: Fix IOMMU window check).

This is still happening to me after an update minutes ago:
