It turned out to be a configuration issue (as expected). My routine of "cp ../`uname -r`/.config .config; make oldconfig" did not do the right thing when doing that upgrade - I ended up with # CONFIG_CPU_FREQ_GOV_ONDEMAND is not set CONFIG_X86_SPEEDSTEP_CENTRINO=m CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y which resulted in speedstep being disabled with no obvious clues what to do to turn it on. After some poking, I'm now running 2.6.17-rc1-mm3 with CONFIG_CPU_FREQ_GOV_ONDEMAND=m CONFIG_X86_SPEEDSTEP_CENTRINO=y CONFIG_X86_SPEEDSTEP_CENTRINO_TABLE=y and everything is working fine. -andy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
