Ike,
Still no luck with the latest kernel. Rfkill is still not showing
anything, and blacklisting acer_wmi has no effect.

Hi,
The last approach introduce regressions, so I am thinking an alternative
approach. Since most of the report is on ideapads or thinkpads, and we
have rfkill registered in ideapad-laptop, I think it will be fine not to
register acer-wmi rfkill if we find ideapad/thinkpad device in DSDT.
Ref:
Installed the kernel, rfkill show acer-wireless being softblocked.

Wifi did not work the first time, or after blacklisting acer_wmi. rfkill

You may find the kernel debs at

Ike,
I'm not seeing the kernel (836865-3) resolve the issue. 2.6.38-13.52 is
the kernel in use though, while your kernel is 2.6.38-12.51. Is the
installed kernel the correct one?

After install the kernel and reboot, could you please attach output of

That's bad news. Looks like the only way to fix this is to blacklist
acer-wmi. I will check discussions on platform-x86 and see what's the
proper way to blacklist.

If the softblock is still there and no way to disable is. It would be

I remember that. Once he says that acer-wmi blocking wifi with thinkpad

solve this is to block acer-wmi.
Ok. So far what I know is that there are several exception rfkill
handling in acer-wmi, I will try to put them in dkms
