I have PHOENIX bios version 0.9, the mother board is VIA K8XXXX (I don't remember precisely, i'll check) I noticed a weird thing, I made some test making my system shutdown while 'make -j6 buildworld'. I've made plots for both acpi_ppc and powernow w/ powerd. http://galera.ii.pw.edu.pl/~mkoziej/bsd/acpi_ppc.gif http://galera.ii.pw.edu.pl/~mkoziej/bsd/powernow.gif Please take a look, blue dashed line - cpu yellow - tz1.temp - cpu green horizontal tz1._PSV red - tz0.temp - hd propably blue horizontal tz0._PSV All data is read via sysctl every 0.5 sec. Notice how the temperature readings rise when the system shutdowns because of overheating. The funny thing is, it shutdowns not because of tz1 (cpu), but tz0, which jumps to critical value (???). for powernow/powerd tz0=65 tz1=77 cf=2417705519 tz0=65 tz1=77 cf=2417910721 tz0=65 tz1=77 cf=2415936702 tz0=65 tz1=88 cf=2416307446 tz0=65 tz1=88 cf=2416576021 tz0=65 tz1=88 cf=2417039114 tz0=65 tz1=88 cf=2417932171 tz0=65 tz1=88 cf=2418087771 tz0=65 tz1=88 cf=2501617153 tz0=65 tz1=89 cf=2417387431 tz0=65 tz1=89 cf=2416360118 tz0=65 tz1=89 cf=2418412904 tz0=65 tz1=89 cf=2416242706 tz0=65 tz1=89 cf=2418159100 tz0=65 tz1=89 cf=2421253299 tz0=65 tz1=91 cf=2086969428 tz0=80 tz1=95 cf=1833956647 tz0=80 tz1=95 cf=805414225 tz0=80 tz1=95 cf=805840001 tz0=80 tz1=95 cf=839116645 tz0=80 tz1=95 cf=805418729 tz0=80 tz1=95 cf=805362461 tz0=80 tz1=95 cf=805716574 tz0=80 tz1=95 cf=805477377 tz0=80 tz1=95 cf=805388821 for acpi_ppc (no CPU throttling): tz0=59 tz1=88 cf=2401379699 tz0=59 tz1=88 cf=2401380510 tz0=59 tz1=88 cf=2401381583 tz0=59 tz1=89 cf=2401382351 tz0=59 tz1=89 cf=2401378420 tz0=59 tz1=89 cf=2401379007 tz0=59 tz1=89 cf=2401380296 tz0=59 tz1=89 cf=2401380889 tz0=59 tz1=89 cf=2461789255 tz0=59 tz1=90 cf=1901011303 tz0=59 tz1=90 cf=2401381292 tz0=59 tz1=90 cf=2401376480 tz0=59 tz1=90 cf=2401379591 tz0=59 tz1=90 cf=2465842741 tz0=60 tz1=90 cf=2401379681 tz0=60 tz1=90 cf=2401378740 tz0=60 tz1=90 cf=2401378363 tz0=60 tz1=90 cf=2401381539 tz0=60 tz1=90 cf=2401381739 tz0=60 tz1=90 cf=2463364678 tz0=60 tz1=90 cf=2401377334 tz0=60 tz1=90 cf=2403215458 tz0=80 tz1=95 cf=2301234467 tz0=80 tz1=95 cf=2401381742 tz0=80 tz1=95 cf=2401379380 tz0=80 tz1=95 cf=2401380799 tz0=80 tz1=95 cf=2334049734 tz0=80 tz1=95 cf=2314373696 tz0=80 tz1=95 cf=2401378620 tz0=80 tz1=95 cf=2401379990 tz0=80 tz1=95 cf=2401381876 tz0=80 tz1=95 cf=2401382279 tz0=80 tz1=95 cf=2420919814 The message is: Mar 1 14:06:12 carnivore root: WARNING: system temperature too high, shutting down soon!
