I had the same trouble after I upgraded to Gutsy. I did some homework and found out that yes speedstep-centrino is depricated in favor of acpi-cpufreq. One side effect of this, at least on my laptop, was that speedstep-centrino worked without SpeedStep being turned on in the BIOS. So when the new kernel was trying to load acpi-cpufreq it found that SpeedStep was disabled and didn't load it. That's why there weren't any errors.
So I went into the BIOS set SpeedStep to automatic and now it works flawlessly. Hope this helps. -- speedstep-centrino driver not working on Pentium-M with ICH6 chipset - acpi-cpufreq driver used instead https://bugs.launchpad.net/bugs/120759 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
