AMD Athlon X2 64 5000+, 8GB ram Mandriva 2010.2 32 bit 1. mandriva kernel 2.6.37 32 desktop 32 bit list of profiles : ondemand, powersave, conservative, userspace, performance list of enable frequencies : 2.60 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz ondemand works well : i see it chooses different frequencies along time 2. mandriva kernel 2.6.37 32 server 32 bit (to use 8GB) or MIB Kernel desktop with pae (to use 8 GB) 32 bit, 3.0.x, 3.1.x, 3.2.x list of profiles : userspace,performance list of enable frequencies : 2.60 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz if system uses performance profile no freeze or reboot pb but then system uses only 2600 MHz. cpufreq-info says : it can choose any frequency if at boot system loads cpufreq_ondemand module and uses "ondemand profile" then at boot or during kde session after a brief time (5 s, 5mn, 10 mn), system reboot by itself ! or during opening a kde session or during kde session system freezes. before freezing we see different frequencies are used note :system can works without pb during a day but freezes next day ! same pb with mandriva 2011 64 bit, Mageia 64 bit with kernel 3.0 or 3.3 thanks in advance -- Philippe ROUBACH -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
