Could you advise how to fix this error that is spamming dmesg?

Bump.

[dino99]

Seems a new bug regression into the kernel about nforce2 (maybe its not included, check the kernel module to know if it exist)

http://ubuntuforums.org/showthread.php?t=1680530

[cipherboy_loc]

Lol, I saw that, no ATI hardware here, and stock Ubuntu kernel. The blog that supposedly held the solution for ATI is no longer available. In other words, it appears to be a regression, is there something to fix it?

[dino99]

already reported but expired

https://bugs.launchpad.net/ubuntu/+s...x/+bug/1015165

and that older one

https://bugs.launchpad.net/ubuntu/+s...ty/+bug/852972

[cipherboy_loc]

So the other guy traced it to the nouveau driver, but says that an update resolved it. My system is up to date running 12.10. Wonder what fixed the bug in the earlier version.

yes but what im seeing with your output is related to nforce2. So the question now is to know if the actual kernel still drive that chip or not (which is called a regression). If its not a kernel issue , then the problem is with the video driver.

you have to check if nforce2 is a known kernel module (modprobe) and loaded. And try with some other kernel(s) and video driver to see the difference for narrowing down that issue.

[cipherboy_loc]

Okay, so I am going to leave this open for a bit more on the off chance it isn't fixed, but thus far, across 4 different boots today, I have not encountered any problems with the spamming, so keep your fingers crossed.

[cipherboy_loc]

Marking as solved. No further issues.

Hate to semi-necro a thread, but exactly what was the solution?
