Comment 15 for bug 1535048

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.
