System Information
Ubuntu 18.04 x64, Radeon HD7770

Blender Version
Broken: 2.79b, blender-2.79-4b0b91aee07-linux-glibc219-x86_64, 2.80 Alpha2 hash cc92d83d39
Worked: ?

Short description of error
Can't view/edit particle texture keyframes (e.g. Clouds: NoiseSize/Colors/ImageMapping/ImageSampling, Blend: Colors, Blend, Distorted Noise: Colors, Distorted Noise, etc. ...) without a trick in 2.79.
Influence/Mapping properties of particle texture always seem to work (setting a keyframe there can also help showing the invisible keyframes).

Exact steps for others to reproduce the error
In the default scene with the cube selected,
switch main window to Graph editor
go to particles tab in properties editor,
add a particle texture
go to texture properties
press I to add a keyframe to any property (not Influence/Mapping)
In the Graph editor, it is not displayed.
Now in 2.79x, if I add a keyframe on a particle system property (or particle texture Influence/Mapping property), the texture keyframes will be displayed in the Graph editor and they remain visible even after deleting this "helper keyframe". Also keeps working after saving/closing blender/reopening the file.
But in 2.80, the "helper keyframe" trick does not work. While the keyframes are visible in the graph editor without that trick, there is only the higher-level channel "Particle settings" but the subchannel Texture and the appropriate properties channels (with the eye buttons) are missing, so if there are keyframes on multiple properties you won't know which is which.

At least that seems to have improved since, so the 2.79 trick seems to work now.
Rest still holds true though.
