I too have the same system and same bug as the original post: Dell Latitude X1 notebook. This problem began for me when I upgraded from Feisty to Gutsy.
My kernel is: 2.6.22-14-generic I scanned through Related Bugs: Bug #93404 Bug #67341 Bug #132271 all have similar problems, but can't find exactly my situation as for me the problem is much more sporadic. Sometimes I relaunch powernowd and the scaling works for awhile up to the system max of 1100MHz, then after awhile I only have 600MHz and 800MHz, then it just locks onto 600MHz. As far as I can tell, without reboot or restart of powernowd, the issue does not self-resolve. Although, as I type this, I see the CPUfreq applet suddenly display 800MHz. I still cannot get to 100%. Please note that the X1 has no fan and CPU temperatures run high. Idle in a cold room is 52C, 1100MHz in this same room can get as high as 70C. -- cpufreq locked in slowest speed https://bugs.launchpad.net/bugs/88899 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
