Tested-by: Carsten Otto <otto@informatik.rwth-aachen.de> # 3.2.21, Asus UX31A
More precisely, Carsten was unable to use asus_wmi, getting the following message from a distro kernel based on 3.4.1 and from unpatched 3.2.21:[1]
| asus_wmi: Can't find DSTS
After applying the patch described above to 3.2.21, multimedia keys work.
| The patch works, dmesg before and after are attached. | | With the patched kernel I can (at least) change the volume using the | Fn keys, gnome shows some audio related icons and a changing (volume) | bar. I did not try further than that (yet).
This is on an Asus Zenbook Prime (UX31A). acpidump, logs, and other info are at [1]. Could you remind me when this hits mainline so we can make sure it gets applied to earlier kernels, for example by adding "Cc: stable@vger.kernel.org" to the commit message?
Thanks and hope that helps, Jonathan
