The processor in that laptop is pretty weak. It is only a single module (two integer cores) AMD and is thus less capable than a similarly clocked Intel i3.
I have no idea what "Even though i use a Roland ua25-ex that stands undisturbed upon its interrupt line..." means since that device is USB based and thus by definition cannot have it's own interrupt. I have a Tascam US122l kicking around. I will see what kind of latency I can get on my AMD machine. It might take a couple of days. Historically it has only been really stable in and around the 10 ms mark.
