If there is No fan rules, the fan is still possbile to be controlled implicitly by other AML method. Otherwise, ACPI is fully exempted from this issue. You need to customize DSDT to figure out which methods could be related to FAN. Maybe there are some potential ACPI interpreter bug causing this issue. Don't know so far. Could you spot it for me?

Some think strang happened with new kernel. Alone fan not working and i wrote driver for i2c chip max1619 to set some ruls for it. It worked with older 2.6.x and now it working too, but with kerenl 2.6.11-rc1-mm1 fun start but wen it's cold can't stop. I made some tests with fan (for monitoring i used lm-sensors, no ruls seted): --------kernel 2.6.11-rc1-mm1----cold start!!!--fan not working and mus not max1619-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 M/B Temp: 42.00 (temp1) CPU Temp: 42.00 (temp2) temp2_min: -55.00 (temp2_min) temp2_max: 55.00 (temp2_max) temp2_crit: 100.00 (temp2_crit) temp2_hyst: 95.00 (temp2_hyst) alarms: 2.00 (alarms) --------kernel 2.6.11-rc1-mm1----cold start!!!--fan not working but must to!!! max1619-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 M/B Temp: 48.00 (temp1) CPU Temp: 61.00 (temp2) temp2_min: -55.00 (temp2_min) temp2_max: 55.00 (temp2_max) temp2_crit: 100.00 (temp2_crit) temp2_hyst: 95.00 (temp2_hyst) alarms: 18.00 (alarms) ------------------------------------------------------------------------------ --kernel 2.6.11-rc1-mm1----hot start!!!(i made "make bzImage && restart")--fan working and must!!! max1619-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 M/B Temp: 50.00 (temp1) CPU Temp: 60.00 (temp2) temp2_min: 50.00 (temp2_min) temp2_max: 80.00 (temp2_max) temp2_crit: 100.00 (temp2_crit) temp2_hyst: 95.00 (temp2_hyst) alarms: 138.00 (alarms) --kernel 2.6.11-rc1-mm1----continue--fan still working ewen if CPU is cold!!! max1619-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 M/B Temp: 43.00 (temp1) CPU Temp: 44.00 (temp2) temp2_min: 50.00 (temp2_min) temp2_max: 80.00 (temp2_max) temp2_crit: 100.00 (temp2_crit) temp2_hyst: 95.00 (temp2_hyst) alarms: 10.00 (alarms) -------------------------------------kernel 2.6.10-mm3----------------------- ---cold start--- fan not working its OK!!! max1619-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 M/B Temp: 48.00 (temp1) CPU Temp: 46.00 (temp2) temp2_min: -55.00 (temp2_min) temp2_max: 55.00 (temp2_max) temp2_crit: 100.00 (temp2_crit) temp2_hyst: 95.00 (temp2_hyst) alarms: 2.00 (alarms) -------------conitue-----make bzImage----CPU hot and fan working!!!!

Yes! Yes! Yesss!!! I'm happy. Thenk you wery mathc. But tis is not in stabil tree. Now i know my mistake. Some times i started linux after win. I think win konfyusd EC ruls and linux take it. If linux start therst then ewery think OK and fan working. If after windows - don't. kernel 2.6.12-rc6. tested fun not working *** Bug 3827 has been marked as a duplicate of this bug. *** i don't have this hardware anymore. |
