The reverts fix 'the interrupt storm issue' that they are causing on 
some systems but don't fix the issue with the interrupt mode not being 
used. I was hoping Jerry would get access to a system faster but this 
didn't seem to be the case. So sending these patches seemed the better 
solution than leaving 5.4.x with the problem but going back to when it 
worked 'better.'
