Please revert this change - my laptop crashes (hard) with the lower limit. I confess that I didn't entirely understand what the erratum meant (and I still don't) when I wrote the N60 errata patch last year, as I'm nowhere near an expert on the Pentium 4 architecture. There may very well be some other change that would enable more efficient use of power on affected systems. The way the kernel's power management code uses the processor now, however, requires the 2 GHz limit.
The erratum is available at the bottom of page 49 of the pdf at http://download.intel.com/design/Pentium4/specupdt/24919965.pdf if someone better at Pentium 4 internals wants to take a crack at a more efficient patch. -- p4-clockmod and "N60 errata" patch https://launchpad.net/bugs/51847 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
