For me (and a few friends as well), user-level ppp will rise the load average up to 1.00 - say about 3 times out of 7. All of a sudden, the load will rise to 1.00, and won't come down until the ppp connection is dropped. The load seems to be "artificially" high, since the CPU is actually 99% idle, and the machine is normally responsive. I ktrace'd it when this happened once, but I lost the output.. perhaps I'll look into how load average is calculated, and see if I can figure out how to debug ppp when it acts weirdly... How should I go about this? Same results under 2.1.0 -> 2.2-GAMMA.
