No, you won't. #UD and #GP will not (I hesitate to say never, but other than a processor bug, I believe that is correct) reset the processor. And CR4 is not "undocumented", even on 486.Yes it is. The i486 Programmer's reference manual documents only to CR3.
The manual might be older than the newer 486 CPUs.And don't forget that not every 486 is Intel. There are at least Cyrix, AMD and UMC with interesting Am5x86-P75 and Cx5x86 too.
