Adrian,

not yet, for several reasons:
1- as I explained, I can't realy force the problem, it happens when we run some
zfs scripts, like mirror, but have to wait till enough changes happened on
the source, usualy after 24hs.
2- changing to LAPIC seems to have solved the problem.
3- I'm now learning all I can about event timers and you have not answered some
   of my questions :-)
