In my understand, the driver recognize the CPU properly.

Can you try to check also follows? /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq With this driver, it will significantly slow down by setting powersave mode. It seems some bus in the driver. Thank you for report. Hiroshi -- Hiroshi Miura --- miura@da-cha.org, Mobile --- himo@da-cha.org NTTDATA Corp.
