kernel upgrade radeon "GPU lockup CP stall"

[Grant Bowman]

Description: Ubuntu 12.04.1 LTS
Release: 12.04

I ran apt-get dist-upgrade and moved from linux-image-3.2.0-30-generic version 3.2.0-30.48 to linux-image-3.2.0-31-generic version 3.2.0-31.50. Upon reboot I had a black screen. Even virtual terminals didn't work. Rebooting back to -30 made the machine usable again.

After looking in /var/log/kern.log I googled for: radeon ubuntu 12.04 "GPU lockup CP stall"

Several Ubuntu bugs came up with some random, some suspend/resume related and some boot video problems: 986524 936159 980019

This upstream bug indicates that a kernel change exposed a bug in the driver/mesa/drmlib : https://bugs.freedesktop.org/show_bug.cgi?id=45366

Attached is some relevant apport-cli --save results.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and 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.

I will try that when I have time.

I have compared booting -31 and comparing the -30 kern.log results. I have attached the difference in output. It begins:

Pending mainline test results.

I am unclear how to perform the requested test and it seems some docs need updating.

I read the instructions provided but am not clear exactly how to perform the requested test with a mainline kernel. I also haven't had time to do this test until now so the versions you might want tested have probably changed. I read https://help.launchpad.net/Packaging/PPA/InstallingSoftware but wasn't clear if just running "sudo apt-add-repository ppa:kernel-ppa/ppa" was enough. Adding the ppa it gave a warning:

You are about to add the following PPA to your system:
 Ubuntu Kernel Team Daily Build PPA - this PPA typically contains experimental packages. The quality of these packages is such that you had better know what you're doing. Don't come crying to the kernel team if it kills all of your kittens.
 More info: https://launchpad.net/~kernel-ppa/+archive/ppa

The information at that URL talks about Lucid, not Precise.

running apt-get update now gives these errors which leads me to believe more is required somewhere.

Thankfully booting the 3.2.0-39-generic kernel works fine.
