Hi,
there are problems on laptops if the smbios.chassis.type is not directly
mapped from the smbios to 'laptop' (e.g. smbios tell it's 'Unknown').
In this case HAL currently call as next coldplug_synthesize_events() after the
smbios probing and first then start to synthesizing the ACPI events/devices.
But in the ACPI code HAL set system.formfactor=laptop, if it isn't already
detected as Laptop (e.g. if the machine has a battery).
The problem is: all other devices as e.g. the WLAN device get synthesized
before the ACPI devices. Hence all fdi-file checks for laptop can fail with
the result:
* the properties get not set
* e.g. the IPW killswitch device get not spawned
* the ACPI input devices as e.g. lid/power/suspend button are not setup
The attached patch fixes this problem by synthesize the ACPI events before
call coldplug_synthesize_events(). It worked for me and I could not find any
problems in lshal.
