Hi, I am using Arch linux with kernel 4.2 and the issue is still present. It cause my one core to run 100% load withou any process using it (htop) and draws my battery quickly :( I didn't had an issue with kernel 3.13 AMD A8-4500M APU with Radeon(tm) HD Graphics Log ``` Nov 26 16:30:25 NORMANDY kernel: ACPI: Preparing to enter system sleep state S3 Nov 26 16:30:25 NORMANDY kernel: ACPI : EC: EC stopped Nov 26 16:30:25 NORMANDY kernel: PM: Saving platform NVS memory Nov 26 16:30:25 NORMANDY kernel: Disabling non-boot CPUs ...
