Note that I am using the ULE scheduler. Have you tried not touching the mouse & playing mp3 music do you also hear sound interruptions after a few minutes ? As well as the people talking re. mouse (BTW Kris asked current@ recently if anyone had time to look at Giant lock); Others hear sound interruptions: I wonder if there may be some commonality as well as/beyond mouse locking, in scheduling/locking etc. I've heard sound interuptions on kernels with both schedulers, (but my hosts are sensitive as slow & with DMA off (else wont boot), & I must review my configs some more). -- Julian Stacey.
