And few hours ago I get the third report says the similar issue.

If there is VPC2004/IBM0068/LEN0068 in DSDT, then it will be fine if we do not register rfkill in acer-wmi. > > Any thought? > Yes, it's possible a solution. If you can make sure lenovo machines have VPC2004/IBM0068/LEN0068 in DSDT, then I will generate a patch to acer-wmi.
