Trouble shooting ideas:
One first step is to plug in another keyboard, to determine if it is hardware, or a software problem.
That might narrow it down.  Keyboards should have an auto repeat, but, also, a diode to provide spike suppression that can result in one key press being echoed multiple times.  

If changing the keyboard out (or using a separate USB/wireless keyboard) doesn't
show any cure, then it would probably be either in the keyboard encoder internal to the computer, or the keyboard software/firmware/bios.  

That is my best offer based on over 52 years in hardware troubleshooting/analysis with over 20 years in the Air Force as a Cryptographic Systems Technician in 17 nations, on the ground, and in the air, plus, in the engineering level R&D and field service for IT companies.   

I refurbish over 400 computer systems annually, (since 1997) taking in donated/broken computers, repairing/replacing all the hardware (down to the component level), and testing, removing all the proprietary lock-in OSes and problematic software, and installing Free, Open Source Linux and/or BSD, for use in homes, businesses, schools and charities.

I have have a Dell Inspiron 11 3000 with Ubuntu installed. If I hit the Fn-PgUp, it goes
page up a whole bunch of times. The page up key is combined with the up arrow key. I hold
the Fn key to get page up.

Any tips?

Thanks, 

brian

Oddly I have a Latitude e7220 that I get this on almost constantly 
across all keys, that it'll just repeat to infinity on at times after 
furious typing and/or backspacing.  Hitting two keys at the same time 
seems to trigger it.  I'm amazed I haven't thrown it across a room at 
times, but I really do like the device otherwise that I've learned to 
almost just deal with it.

I figured it was more a defective keyboard I've been too lazy to try and 
deal with clueless dell support with testing anything around linux, but 
interesting others see this too.  Maybe some sort of hardware or 
acpi/bios level defect?

Have you tried a live CD of any other Gnu/Linux distro?

Have you tried a Kubuntu live CD?

This would go a long ways to finding where the problem actually is.
