I have no experience using more than 4 GB. What was the issue with 64-bits
kernels?

I was thinking a 64 bits kernel is better than PAE when there is much
memory.
In this interview
http://www.itwire.com/opinion-and-analysis/open-sauce/44975-linus-torvalds-looking-back-looking-forward?start=2
Linus say: "there's no way to ever really get the Intel PAE model to work
perfectly"

Later on page 5
..."
The whole "support memory past the 4GB mark on a 32-bit architecture" thing
is something I absolutely hate. It impacted _everything_. It was really
painful, and people trying to run 32-bit x86 processors with 32GB of memory
was just a total disaster.
We could do it, but it was a memory management nightmare. And I was really
unhappy with how Intel seemed to drag their feet on the whole 64-bit side,
pushing instead their crazy and fundamentally flawed Itanium architecture.
Then AMD came around with x86-64, and there was finally light at the end of
a long, dark, nasty tunnel.
