I see something similar, as a file is generated during a compile a get a
momentary hang in the mouse, but it is not every compile. I think I see it
mostly when running some invocation of make -j, but I've not been able to
lock down a particular set of circumstances where I do see it. My
sched_ule.c is at 1.80. I have a UP system. This behaviour, intermittant
though it is, persists across a normal UP kernel, and also one with SMP+APIC
(I was *supposed* to have two CPUs, but that is another issue ...) enabled. I
have a PS/2 mouse and use moused. I'm running KDE3.1.4.
