Hi Joey, sorry for replying late.. For ideapad s205, I work with bug reporter at http://launchpad.net/bugs/875659 The bug reporter do not attach the DSDT, but I have a copy of acpidump of s205 at http://people.canonical.com/~ikepanhc/DSDTs/acpidump-ideapad-s205.dat and I backport this patch to 3.0 kernel and also cherry-pick acer-wmi: check wireless capability flag before register and get the report which says the rfkill:phy0 is hard blocked by mistake https://bugs.launchpad.net/ubuntu/+source/linux/+bug/875659/comments/33 so that I have another kernel built without touching ec register, just dont set ACER_CAP_WIRELESS and user reports everything looks fine. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/875659/comments/43 For ideapad s12, I work with bug reporter at http://launchpad.net/bugs/668234 You can find acpi tables at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/668234/+attachment/1715424/+files/AcpiTables.txt With patched kernel, rfkill:phy0 is also hard blocked by mistake and it can be unblocked by toggling the hardware radio switch https://bugs.launchpad.net/ubuntu/+source/linux/+bug/668234/comments/12 Again, I need to confirm its because we touch the ec register, so I ask them to blacklist acer-wmi. User reports it looks fine, but rfkill:phy0 hard blocked after couple of seconds and no idea why. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/668234/comments/16 On 01/12/2012 08:21 AM, joeyli wrote: > 於 四,2012-01-12 於 00:54 +0800,Ike Panhc 提到: >> On 01/11/2012 12:26 PM, joeyli wrote: >>> 於 一,2012-01-09 於 22:15 +0000,Carlos Corbacho 提到: >>>> On Monday 09 Jan 2012 18:00:24 joeyli wrote: >>>>> I just checked and found I also have no AMW0_GUID2 machines on my hand, >>>>> now. >>>>> I have some questions about AMW0_GUID2: >>>>> >>>>> + Why we enabled wireless capability in acer-wim if a non-acer machine has >>>>> AMW0_GUID2 ? >>>> >>>> IIRC, there were some bug reports on non-Acer hardware (I don't think this >>>> involved Acer hardware, but this was some time ago...) where the wireless >>>> detection wasn't working with this, but if we forced it on, it worked fine. >>>> >>> >>> Yes, in acer-wmi supported some non-acer machine by quirk and read EC >>> register.
