** Description changed: + SRU Justification + + Impact: The wlan on the Acer Aspire 1830 always has a soft block applied + due to incorrect values read from the BIOS on periodic updates. + + Fix: Backport patch that makes this model use WMI events to update + rfkill states instead of periodic polling. Data in WMI events accurately + reflects the status of the blocks. The backport results in a wlan soft + block when pressing the touchpad hotkey, so also include a fix to only + update rfkill states when wireless hotkeys are pressed as well as a + trivial patch to support the wlan hotkey on this model. + + Test case: Verify that wlan soft block can be removed, wlan hotkey + functions, and touchpad hotkey does not affect wlan on the affected + model. Tested on LP #771758. + + --- + On my Acer Aspire 1830-3595 I have the following situation: after installing natty wifi won't work, the wifi is soft block when checking with rfkill the solution was blacklisting acer-wmi module ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-8-generic 2.6.38-8.42 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic x86_64 NonfreeKernelModules: wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
