[STAGING] Alpha 3 Narwhal on MacBook locking up every hour

[Mike]

I have the 64-bit Mac/Intel version of 11.04 (Natty Narwhal Alpha 3) installed in a triple-boot system and Ubuntu becomes unresponsive about once an hour. No way to switch to a terminal or any other interrupt that I know. Must power off, and it reboots fine. Once it generated an error on reboot and I filed that bug.
I've been vigilant about running updates, and it once crashed during the update.

Still happening after another couple days of forcing updates and performing reboots. Probably locked up about 10-12 times now. Let me know if there are any logfiles that might be useful.

[Mike (bild85)]

Further indication that this may be caused by the default "Experimental" video driver:
https://help.ubuntu.com/community/MacBookPro6-2/Maverick#Video%20&%20Effects%20%28Compiz%29

I've switched to the NVIDIA accelerated graphics driver so we'll see if it still freezes.

[Kris Marsh (moogman)]

I don't see this issue on a fresh install on a MacbookPro 6,2 - with Ubuntu 11.04 beta 32-bit - I have not changed from the default graphics driver.

[Mike (bild85)]

It hasn't frozen on me since making the change to the NVIDIA driver.

[Mike (bild85)]

I think the duplicate status is wrong. This is not dependent on a suspend. It happens when using the default video driver for 64-bit. I'll attempt to remove the link to bug #740928.

[Brion Vibber (brion)]

I still get regular crashes after 20-80 minutes of use despite running the proprietary NVidia drivers instead of the default.

[Mike (bild85)]

@Brion - sounds like a different bug, or it could be hardware-dependent. Maybe open a new bug using 'ubuntu-bug' from the command-line. I think I used 'ubuntu-bug linux', but then again, this bug doesn't seem to have gotten much attention, so maybe that wasn't the best choice. Maybe something involving nvidia?

[Mike Wilson (mike-wilson)]

I too am experiencing issues. I am attempting to narrow down the exact parameters. I will update here when I understand the exact configuration. I had crashes with Nvidia installed, but it appears to have gone away. If so, I will post the settings that I changed in xorg.conf.

Mike, thank you for reporting this and helping make Ubuntu better. 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 capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ? As well, can you try 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 run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please 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. Please let us know your results.

Thanks in advance.
