Can't turn off/on bluetooth via acpi in eeepc 901/1000

[Giovanni Masucci]

In ubuntu hardy on eeepc 901/1000 it's impossible to turn off/on the integrated bluetooth.
This patch from daltona solves the issue. It has already been tested in the costum eeepc kernel by Adam Mc Daniel:

I forgot to say that this bug is also present in intrepid kernel 2.6.27, that from what I've understood, doesn't use eeepc-acpi.ko, but eeepc-laptop.ko
OT:
I don't know if there's much difference between the two, I only know that eeepc-acpi seems to work much better than eepc-laptop on my eeepc 901.
With eeepc-laptop osd are very laggy and I also can't control webcam via acpi.
So it would seem that the best solution is to patch eeepc-osd for bluetooth and include it in the kernel instead of eeepc-laptop, but I'm no expert to take such decision.

[Sitsofe Wheeler (sitsofe)]

The issues with eeepc-laptop are related to the EC GPE storm bug changes. There are patches that restore the speed of hotkeys. See http://bugzilla.kernel.org/show_bug.cgi?id=11549 . It looks like eepc-acpi is deprecated and Debian appear to be dropping it - http://<email address hidden>/msg38682.html .

with latest 2.6.27 kernel I can now control the webcam via eeepc-laptop ...bluetooth support is still missing or not working

[Sitsofe Wheeler (sitsofe)]

This is known by the eeepc-laptop devs and in fact the patch for solving this is small (it's just a matter of adding another verb in the kernel driver). It's unlikely the fix will land before 2.6.27 is released though...

Can this issue be reproduced in Ubuntu 10.04?
