This probably needs sysprof instead of oprofile to track it down.  If
it's fallbacks happening, then exa and the 2d driver have debug options
for printing what fell back and why.

Some fixes were just committed by frederickh to replace my lame memory
algorithms algorithms in exa with some better stuff.  Without debug
symbols, I can't tell if that's the problem you were hitting or not.
