I've noticed the same problem with the latest Intel driver versions. It 
doesn't seem to be an issue when running a realtime kernel, but with a 
normal kernel the effect on JACK is pretty bad, especially when using 
FFADO. Even very large JACK period sizes don't really help.

For now I went back to driver version 2.7.1, which still let you choose 
between UXA and EXA (the latter has been removed in 2.8). UXA has the 
problems you describe, EXA doesn't. I'll try to gather some more 
information on this and add it to your bug report.
