I am using gentoo-dev-sources-r11. My CPU is a Pentium-M 745 (1.8 GHz). I see the following message in dmesg: speedstep-centrino: found unsupported CPU with Enhanced SpeedStep: send /proc/cpuinfo to Jeremy Fitzhardinge <jeremy@goop.org> # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.80GHz stepping : 6 cpu MHz : 1794.668 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe tm2 est bogomips : 3555.32
I meant gentoo-dev-sources-2.6.7-r11.
I've updated to gentoo-dev-sources-2.6.8 and I still get the same message in dmesg: speedstep-centrino: found unsupported CPU with Enhanced SpeedStep: send /proc/cpuinfo to Jeremy Fitzhardinge <jeremy@goop.org>
Great, I suggest you follow the instructions the kernel is telling you to do. This is an upstream kernel.org issue. Please contact the email address that the kernel is asking you to, there's nothing the gentoo developers can do about this, sorry.
