At least for Intel it's definitely not true. AER goes back a
lot of generations, pretty much all that support PCI Express. 

There were some bugs in it of course and some workarounds needed, but
no show stoppers in any particular part to my knowledge.

Haven't kept fully track of AMD systems recently, but would surprise
me if it was the case on AMD either.

This applies to servers. On clients AER is more spotty
and various simply don't have it.
