That's interesting. While our systems are different enough that direct 
comparison isn't necessarily useful (fedora vs gentoo, I'm running live-
git kde from the gentoo/kde overlay and have no polkit, my kernel is pure 
Linus git upstream), I'm all radeon here and have seen nothing like you 
mention for quite some time.  So it's quite interesting that your radeons 
got through the upgrade fine while the intel graphics didn't.

Based on that I strongly second RJVB's suggestion to focus on testing the 
fc38/39 intel graphics differences.

But let me add mesa and libdrm to the kernel and kernel and/or module 
command-line he mentioned.  Both of them have graphics-driver components 
and intel regularly contributes a good portion of the libdrm changes in 
particular, so comparing versions and fedora-specific patches between 
releases there could be worthwhile.

But kernels are designed to be interchangeable and upgradable (within 
reason) without affecting userspace, while mesa/libdrm are more likely to 
have version dependencies complicating things (tho FWIW, here on gentoo 
neither package is subslotted, indicating version-deps aren't particular 
enough to normally require any rebuilds on up/downgrade, so I'd not 
anticipate /major/ problems trying to test older/newer versions of either 
package).  So a kernel-first testing focus still makes sense.  Sure, 
quick-check the version number differences just to see how different they 
are, but beyond that, I'd not worry about them unless/until the kernel 
difference investigation turns up nothing.
