Description Roberto de Iriarte 2016-07-27 23:42:17 UTC 
On my Thinkpad T420s, after upgrading from 10.3-Release to 11-BETA2, the suspend button does nothing if acpi_ibm is loaded

Without acpi_ibm the button works as expected

Setting

sysctl dev.acpi_ibm.0.handlerevents='0x04'

Solved the problem

It should be noted that the behavior deviates from 10.3
