Laptop Fans are disabled after Flight 6 Upgrade

Bug Description

After upgrading to Flight 6 on a newly installed Flight 4 install, the fan on my laptop no longer seems to work after X boots.

If I start the machine in rescue mode, the fan fires up OK and keeps the machine ~65degrees.

If I exit the rescue mode, the fan shuts down after the "Checking Battery State" initscript starts.

A standard boot process has the fans running until just before the GDM screen appears, then the fans seem to shut down.

All other ACPI functions (battery life, thermal zone, etc) still work correctly, verified with an 'acpi -t' run.

This results in a hard lock on AC or battery after a CPU intensive process (like Firefox + Evolution) has been running for an hour or so.

The same hard lock can be obtained on AC by running gnome-screensaver with the footlogo-floaters theme.

The dmesg output on the affected machine.

The results of dmidecode.

The results of 'lspci -v'

A straight 'cat /proc/acpi/thermal_zone/*/*' run after the initial bootup in recovery mode.

This woiuld seem to be a power manager issue of some kind. The kernel just does what it is told :)

Could it also be an acpi-support issue? The fans in this particular machine are passively controlled and there's no BIOS functionality to change the temperature based control.

... because i've just had the same lockup appear after 4 hours with GDM sitting on the screen (ie. not being logged in, just powered up)

This isn't a gnome-power-manager bug IMO.

Do you still have the problem with the current Edgy ?
