I was keeping htop open during recording and never noticed anything too crazy. CPU was always about 30%-35% max on each of the 4 cores.
Would you still think it's an interrupt issue if there were no pops and cracks on Windows using the same exact hardware in the same USB port?
- squarefoot 8y agoMine was just an idea. If you're experiencing an extremely short burst that overloads the machine, it could be so short that it disappears when measuring average cpu load which is what most tools do, but it could affect a near realtime buffer write or read (from an audio or network card). If there is any way to plot very short high spikes it should become recognizable, especially if it obeys some regular pattern like a timed irq or the like. In our old case, the hardware were Alpha workstations and Tru64 the OS, we nailed the problem to a driver because installing both Linux and *BSD on the same hardware the problem disappeared, so it can be a software issue.
