Hi; 01 Haz 2007 Cum tarihinde, Linus Torvalds şunları yazmıştı: > Has it been hot where you are lately? Is your fan working? First of all sorry for late reply. For a while İstanbul is not really hot [~26 C] :) and yes fans are/seems working without a problem. > Hardware that acts up under load is quite often thermal-related, > especially if it starts happening during summer and didn't happen before > that... ESPECIALLY the kinds of behaviours you see: the "sudden power-off" > is the normal behaviour for a CPU that trips a critial overheating point, > and the slowdown is also one normal response to overheating (CPU > throttling). According to ACPI output; [caglar@zangetsu][~]> cat /proc/acpi/thermal_zone/THRM/* <setting not supported> cooling mode: passive <polling disabled> state: ok temperature: 56 C critical (S5): 105 C passive: 95 C: tc1=1 tc2=5 tsp=10 devices=0xc20deec8 105 C is critical for that CPU, for a while (this is why i reply late) i'm constantly monitoring the temprature under low and high load. Its in 50-70 C interval in normal usage/idle and 80-100 C interval under high load (compiling some applications, using cpuburn to test etc.), so seems it can handle overheating issues But digging the kern.log shows some strange values also; May 24 10:39:23 localhost kernel: [ 0.000000] Detected 897.748 MHz processor. <--- 2.6.21.2-CFS-v14 ... May 30 00:59:11 localhost kernel: [ 0.000000] Detected 898.726 MHz processor. <--- 2.6.21.2-CFS-v15 ... Jun 1 02:09:44 localhost kernel: [ 0.000000] Detected 897.591 MHz processor. <--- 2.6.21.3-CFS-v15 ... And according to same log these slowdowns occured after i compiled/installed these kernel versions into system(cause these are the first appearence of this versions in kern.log). So as you said it seems definetly a overheating issue. I'll continue to test/monitor and report back if i can find anything. Thanks!
