AFAIK they patch known vulnerabilities and obvious bugs (as reported in 
bugzilla.redhat).

Any info on which ones?

A very very long time ago in another universe I used to add the rt 
patches on top of plain vanilla kernels, but eventually switched to 
keeping the Fedora patches to make the kernels more compatible with the 
ones installed by default. It also makes it a snap to use their .src.rpm 
builds as a base for mine (I do an emacs ediff to merge changes each time).

I use my own RT patches kernels (with the Fedora patches) in production 
all the time with no ill effects that I can detect. For the work I do I 
really need the RT patches - while the stock kernel has gotten much 
better it is still not enough, even with "threadirqs" enabled and proper 
irq prioritization.

(when I upgraded our Listening Room diffusion control system I really 
tried to use stock kernels but could not, for example an ssh into the 
machine would pretty much always trigger a bunch of xruns...)

Poor little floppies!

(I still have a few 8 inch floppies for old time's sake - they used to 
boot the OS of the synclavier they had at LIPM in Argentina :-)
