Hi Tolan, Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please 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 95569 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. [This is an automated message.

I am dissappointed that this bug has been marked as low importance and won't fix. The problem still exists and it's quite serious, even if it seems to affect only to a limited number of people. Setting cpufreq_ac_policy to conservative in gnome-power-manager does not completely solve the problem. It simply makes it very less frequent. Obviously the hang happens when CPU frequency changes and these frequency changes are less frequent in conservative than in ondemand. -- CPU frequency scaling causes crash https://bugs.launchpad.net/bugs/95569 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 95569] Re: CPU frequency scaling causes crash
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel.

[Bug 95569] Re: CPU frequency scaling causes crash
I am also experiencing crashes related to CPU frequency scaling. I have a dual core processor (Core 2 Duo E6600) and every time I run a heavy process the computer freezes once the process is finished and load goes to zero. If I run e.g. glxgears with nice 19 in the background, this does not occur. I can also fix this by saying sudo chmod +s /usr/bin/cpufreq-selector and setting both cores to performance (i.e. full frequency all the time). This happens both in edgy and feisty. However, one of the first Feisty alpha kernels did not have this bug. If I remember correctly it was 2.6.19-7. My motherboard is Abit AB9 with latest BIOS. I also have another similar system, but with a different motherboard (Asus Commando).
