------- Comment #13 from [EMAIL PROTECTED] 2007-09-02 04:14 ------- New info: 1) Without new DSDT 2.6.23-rc5 with debug patch - cooler is always on - cooler is on after resuming from S3 - 'cat /proc/acpi/fan/FAN/state' always say 'status: on' - 'echo 3 > /proc/acpi/fan/FAN/state' does nothing - 'echo 0 > /proc/acpi/fan/FAN/state' does nothing 2) With new DSDT 2.6.23-rc5 with debug patch - cooler is always on - laptop doesn't go to S3 (IMHO the reason is debug patch) - 'cat /proc/acpi/fan/FAN/state' always say 'status: off' - 'echo 3 > /proc/acpi/fan/FAN/state' does nothing - 'echo 0 > /proc/acpi/fan/FAN/state' makes really much noise is system log. The messages doesn't stop at all. The fan is still running, the 'echo' command doesn't exit properly. 3) With new DSDT 2.6.23-rc5 without debug patch - cooler is on after boot - after resuming from S3 cooler is off - 'cat /proc/acpi/fan/FAN/state' always say 'status: off' - 'echo 3 > /proc/acpi/fan/FAN/state' does nothing - 'echo 0 > /proc/acpi/fan/FAN/state' stops the cooler. The output of the command is "echo: write error: Exec format error" Next time when I execute this command, cooler starts for a second and then stops again. If I try to execute this command after 'echo 0xffffffff >/sys/module/acpi/parameters/debug_level', I also get infinite number of messages in syslog, and the 'echo' command doesn't exit properly. The way to finish 'echo' execution and to stop getting syslog messages is 'echo 0x0f >/sys/module/acpi/parameters/debug_level'. However in this case the fan is not always off. After some time of idle it starts again for a few seconds and then stops. I analized this behavior for a while with 'watch -n 1 cat /proc/acpi/thermal_zone/THRM/*' and I guess that fan starts when CPU temp is more than 50C and then stops when the temp is under 50C. Seems almost ok, but in my mind it would be more effective to lower the temp to 45C for example and only then stop the fan. I will attach dmesg logs now. -- 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. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
