Thank you for your work) 
The keyboard is http://www.samsung.com/us/support/owners/product/BKB-10USWEGXAR
Once it is paired it just becomes unstable. Big latency, and also Bbbuuuuugs liiike thisss. That particular bug is making it unusable. Also i was checking it in kacpimon, if acpi sees several key presses also, and it does. While that laggs there are no any errors at all in syslog or dmesg, only after disconnect. And it is not disconnected right after pairing. It is very random, but sometimes before error about disconnect drm:intel_pipe_update_end [i915] bug appears, sometimes not. Also important to mention that with windows 10 it works perfectcly (fast, stable, no disconnects). Every Bluez install i was installing with bluetooth library, but now i will try to work with native 5.37 lib and old and stable bluez to find if it is bluez or lib bug. A bit later i will give you my logs with buggy and with stable bluez. syslog with disconnect after intel error:

Title:
  Bluetooth mouse laggy and erratic

Status in bluez package in Ubuntu:
  Confirmed
Status in linux-firmware package in Ubuntu:
  Confirmed

Bug description:
  I installed Ubuntu 15.04 (64 bit) on a DELL XPS 13 (model 9343, bios
  A03) notebook. I use a DELL bluetooth mouse but sometimes it behaves
  erratically (laggy, jumpy). The problem happens after a few (sometimes
  one) suspend and resume. I am attaching below some info on my system.
  Thank you.
