SysRq-t with last patch

I cant get mouse cursor freeze after the last patch. and my hand is tired. And
not sure about iowaits anymore. Sometimes they happen and i tried to catch them
with SysRt-t but something changed in those trace or i failed to catch the
right moment.
Screen still stops refreshing. Mouse cursor moves fine and CPU load looks ok
most of the time. But everything is still as laggy as before.

My CPU Core™ i5-3450 doesnt support VT-d.
