Keep an eye on the interrupts while its all running, particularly
Non-maskable interrupts. Try to correlate them with the 0.6 sec
of the glitches if possible;
watch -n 0.1 cat /proc/interrupts
I've written up some of the checks I generally do, perhaps browse
that to see if there's anything there that you could check?

Thats all I can think of at the moment, -Harry
