------- Comment #12 from [EMAIL PROTECTED] 2008-07-14 06:47 ------- Hello, Following you recommendation, I modified DSDT.lst to get rid of the thermal warning and to get the processor better cooled and correct some warnings. I can now run a "make -j8" without fearing cpu overheatings. Also, I read the ACPI Thermal Zone spec. The draft was quite old (2005) but helpful and still greek to me. Sorry, if what follows is totally wrong. Abit FanEQ features help to select the temp source to regulate the SYS fan as well. You can select SYSTEM or CPU as source. I guess that is the clue of the linux thermal warning. Linux acpi supposes that the _PSV has just a fixed value. It is not the case with the Abit AX78 motherboard. _PSV is shared and gives two different temperature values TP1H or TP2H according to the PLCY value Or(PLCY, PLCY, Local7). I although added _ACx and _ALx. I could have defined a better value for _AC0 and used a multiplier like the "FanEQ Temp Tolerance" Abit bios option. _AC0= _PSV * 1.05 for instance or use the "Temp Tolerance" directly. But it has not been defined in an ACPI variable and I am not used to the ASL syntax :( I still believe linux thermal should be more flexible and accept that the _PSV value could be a variable and not consider the changing of the ACPI thermal trip point state like an error but rather as a common warning and re-evaluate via the AML code (Notify(thermal_zone, 0x81)). Beside, I read (probably in an lm_sensors archive forum) that reading _RTMP is not always accurate and will lead to unexpected behaviour if the value is over the _CRT one. It is preferable to deactivate _CRT in thermal kernel module with the option nocrt. Otherwise, for no real reason the computer will stop. It happens to be me. In case that could help someone, here is the dsdl.dsl.diff file i'm using now. PS: I abandoned the idea to create a new "group" of components that will be managed with the others fans available. I was unable to create a working fan device for it :(. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
