System Information
Operating system: Ubuntu 18.04.1
Graphics card: AMD RX 580 (8GB)

Blender Version
Broken: 2.80.44, d3870471ed, 2019-02-12

Short description of error

Blender crashes when entering rendered mode in viewport with a particles system.

Open default scene and append a particles system (i've used the hair type with collection)
Assign that particles system to an object (like a plane in the image)
Switch to Cycles and in the viewport change the mode to rendered
It crashes

I can't reproduce this on my end.
Could you attach a .blend file that crashes for you so we can see that I didn't miss anything?

This is the Particles.blend file where i saved a particles system and assigned to a plane:
Particles.blend
Open a new project, go to File > Append and choose the "Particles Test" ParticlesSettings from the blend file above:
Now add a plane, go to Particles Settings and choose the "Particles Test" particles system from the list
Switch to Cycles render, and enter in rendered mode for the viewport... CRASH
