I don't even trust it to run a hobby spec mill such as a Sherline let alone 
some of the heavy iron I have. Running in an industrial environment is just 
asking for trouble...

Random use of volatile keyword produces bad (binary) code. See what Linus 
Torvalds has to say on the subject at lwn.net.

Conversion between float & double does not produce "rounding errors", it loses 
precision and range. Don't mix'n'match on a whim.

Hiding behind opaque data types - It obscures intent and if you insist on 
using _t suffix, it will lead to namespace pollution/conflicts. See 
Stroustrup, Torvalds, & Stallman for further details.

What mechanisms are in place to prevent a user from unloading any/all modules 
while a system is live & running ?

Can firmware be uploaded on the fly on a live system ?

What critical system variables can altered on a live system, and will it lead 
to a crash ?

What happened to Aunt Tillie - Did someone do the old dear in or was she 
crushed under a mountain of paper ?
