I have reported this problem in many places and searched the internet a long time for a solution but i can't find some suitable fix. The problem is that i can't monitor and control the sensor chip datas because of the lack of smbus detection. Yet this problem had been solved about 2 years ago when i reported it on this list thanks to the help of Jean Delvare : http://archives.andrew.net.au/lm-sensors/msg29507.html http://archives.andrew.net.au/lm-sensors/msg29523.html I am using now an old mandriva 2006 with kernel 2.6.12-27 that is properly detecting the smbus and it appears on the lspci as : 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 03) But now that i want to jump to a newer distro, none of them is able to detect this smbus in spite of the quirks (see above) that is present in the kernel : $ cat /usr/src/linux/drivers/pci/quirks.c |grep -i w1 case 0x184b: /* W1N notebook */ The same lack occured occured on ubuntu 6.10 , suse 10.1, mandriva 2007 and suse 10.2 with recent kernels ranging from 2.6.16 to 2.6.18 . No smbus is appears on the lspci for any of these distro. I reported this problem here : http://www.suseforums.net/index.php?showtopic=25980 http://qa.mandriva.com/show_bug.cgi?id=25281 But i had no answers. The sensor monitor and fan speed control is a very interesting feature on this laptop for battery saving reasons. I'd be really glad if someone could help . Or please someone point me to a better place to report this problem. Thanks. -- christophe -------------- next part -------------- A non-text attachment was scrubbed...
