Description Tony White 2010-04-15 22:14:07 UTC

Dunno what CWAP(1) is? Could maybe say if it supports it or not if you can say what that is. If it's for a sim card, the M3N doesn't support that feature.

I guess that the problem is that there is no bluetooth on the M3N model, so maybe the module doesn't need to try to detect it?

From dmesg : -

asus_laptop: Asus Laptop Support version 0.42
asus_laptop: Error calling CWAP(1)
asus_laptop:   M3N model detected
asus_laptop: Error setting bluetooth status to 1
input: Asus Laptop extra buttons as /devices/platform/asus_laptop/input/input10
Registered led device: asus::mail

Nothing appears to be broken other than those two error messages, so please treat this report as trivial.

Thanks,
Tony

According to Documentation/laptops/asus-laptop.txt:

         wapf: WAPF defines the behavior of the Fn+Fx wlan key
           The significance of values is yet to be found, but
           most of the time:
           - 0x0 should do nothing
           - 0x1 should allow to control the device with Fn+Fx key.
           - 0x4 should send an ACPI event (0x88) while pressing the Fn+Fx key
           - 0x5 like 0x1 or 0x4
You could try to pass wapf=0
Same with bluetooth_status parameter.

M3N doesn't have an Fx wlan key. So neither WAPF or bluetooth on this model.
I'm interested in why the kernel or udev think it's detected things that aren't present and then trying to use them.
Thanks for checking the documentation for what it does.

I'll try adding the parameters.

Thanks,
Tony

The use of the wapf=0 bluetooth_status=0 parameters make no change to the production of the error messages in the log.

I can confirm this one - got a Samsung P35 which does not have bluetooth and does not have a Fn+Fx Wlan Key (it does have a extra wlan button, but no fn key).
