It's very similar and i do sometimes experience the flickering as a
precursor to the complete crash, but mostly screen goes off and it just
crashes. Actually it freezes the whole PC. Keyboard is unresponsive. I
installed kdump, set soft, nmi etc. watches on but the PC does not
detect the crash and does not boot the second kernel :( and i dont have
a nmi button. All i can is power off and restart. Got ideas, how i can
trigger the kernel dump? Also i did experience the same issue with
15.10. I will add libdrm as affected.

** Also affects: libdrm (Ubuntu)

       Status: New

** Changed in: linux (Ubuntu)
       Status: Incomplete => Confirmed

** Changed in: libdrm (Ubuntu)
