Point of reference, it works well with KDE, but there's something
non-kosher someplace. I've been getting this periodically and haven't
tracked down where or why I'm getting it.
On a different note, SCHED_4BSD causes the kernel to hang hard on
KDE's startup during the loading peripherals phase. I'm not home and
don't have any way of debugging this from a remote machine.
Here's the backtrace for konsole.
