So this is the main suspect: commit 18eab8550397f1f3d4b8b2c5257c88dae25d58ed Author: Venkatesh Pallipadi Date: Fri Jun 15 19:37:00 2007 -0400 ACPI: Enable C3 even when PM2_control is zero On systems that do not have pm2_control_block, we cannot really use ARB_DISABLE before C3. We used to disable C3 totally on such systems. To be compatible with Windows, we need to enable C3 on such systems now. We just skip ARB_DISABLE step before entering the C3-state and assume hardware is handling things correctly. Also, ACPI spec is not clear about pm2_control is _needed_ for C3 or not. We have atleast one system that need this to enable C3.
