DetailsDescription:
Pressing the brightness up/down button once, works fine, multiple presses, or long press act as if I pressed only once for about two seconds. After that, the brightness updates to the new state (considering the other presses), and freeze again. The slider also acts funny, trying to "pull back" to the old position. Scrolling over it acts normally while scrolling down, though it still "pull back" when scrolling up. It starts after upgrade to Linux kernel >= 4.0, so now when Linux-lts was upgraded it starts. The same problem is with regular kernel package (linux). Additional info: * package version(s) - Linux-lts 4.1.8-1 * config and/or log files etc. Steps to reproduce: Try to change brightness on Lenovo Ideapad U33Op |

The problem was fixed in standard Archlinux kernel.
