Boy, I love yum. 2.6.15-1.1831FC4smp kernel is installed now. I ran sensor-detect and got the same output as before. i.e. no driver for smsc47m14x/192. So I did a 'modprobe smsc47m1' just in case and didn't get any error. Output from 'dmesg' was: smsc47m1: Found SMSC LPC47M15x/LPC47M192/LPC47M997 ------- Ouput from 'sensors' now, is: ~]# sensors smsc47m1-isa-0800 Adapter: ISA adapter fan1: 0 RPM (min = 2560 RPM, div = 2) fan2: 0 RPM (min = 2560 RPM, div = 2) -------- Obviously, it's not 0. So I ran 'pwmconfig' and instantly, the processor fans shutoff(because this is SFF, there are 2 fans each side of the heatsink). Here's the output: ~]# pwmconfig Found the following PWM controls: 9191-0800/pwm1 9191-0800/pwm2 Found the following fan sensors: 9191-0800/fan1_input current speed: 5585 RPM 9191-0800/fan2_input current speed: 5461 RPM Warning!!! This program will stop your fans, one at a time, for approximately 5 seconds each!!! This may cause your processor temperature to rise!!! If you do not want to do this hit control-C now!!! Hit return to continue: Testing pwm control 9191-0800/pwm1 ... 9191-0800/fan1_input ... speed was 5585 now 0 It appears that fan 9191-0800/fan1_input is controlled by pwm 9191-0800/pwm1 Fan 9191-0800/fan1_input has not returned to speed, please investigate! 9191-0800/fan2_input ... speed was 5461 now 0 It appears that fan 9191-0800/fan2_input is controlled by pwm 9191-0800/pwm1 Fan 9191-0800/fan2_input has not returned to speed, please investigate! Testing pwm control 9191-0800/pwm2 ... 9191-0800/fan1_input ... speed was 5585 now 0 It appears that fan 9191-0800/fan1_input is controlled by pwm 9191-0800/pwm2 Fan 9191-0800/fan1_input has not returned to speed, please investigate! 9191-0800/fan2_input ... speed was 5461 now 0 It appears that fan 9191-0800/fan2_input is controlled by pwm 9191-0800/pwm2 Fan 9191-0800/fan2_input has not returned to speed, please investigate! Testing is complete. Please verify that all fans have returned to their normal speed. The fancontrol script can automatically respond to temperature changes of your system by changing fanspeeds. Do you want to set up its configuration file now (y)? y /usr/sbin/pwmconfig: There are no temperature-capable sensor modules installed ----- In the beginning you can see that it reports the fan speeds correctly. In the bios, it reports similar values. However, while it is able to successfully shut the fans down, it can't bring them back up(which I verified was true...and bad, so I rebooted into bios). Any suggestions here, it looks like there's a way to detect fan speed and turn it off, now I just need to fine tune it. -Kevin > -----Original Message----- > From: Jean Delvare [mailto:khali at linux-fr.org] > Sent: Friday, February 10, 2006 2:13 PM > To: Williams, Kevin C > Cc: LM Sensors > Subject: Re: Can't load smsc47m1: no such device > > Hi Kevin, > > > My fan speed is at the highest possible speed when booted > into linux > > on this system(same as speed during POST).
