I would have tried it but that is a LOT of updates.  It may be faster to
start from scratch in that case.  I know a few years ago there was some
changes that kept oldconfig from working as it should.  That was the
only time it failed me but I do upgrade more often to avoid this sort of
thing.  I try to upgrade every couple months.  Now if I have long
uptimes, I may not actually ever use that kernel but I have a config
file to copy over that is a bit more up to date. 

I would suggest printing or something the output of the following: 
lspci -k  That tells you what you need for your hardware, that is of
course from a kernel where all your hardware works.  There may be some
specific things for certain software that is needed but at least you can
boot up and have a system to work with.  I usually leave the rest to
defaults unless I am sure there is something I don't need. 

Glad you got it sorted out and working tho.
