I'm not sure exactly what was going on, but it may be that I had some miscompiled kernels... all kernels I was testing with when I reported this were compiled on RedHat 7.2.93 (the skipjack beta) with gcc-2.96. A 2.4.19-pre8 SMP kernel compiled with gcc-3.0.4 does not exhibit this problem. :j -- Jürgen Botz | While differing widely in the various jurgen@botz.org | little bits we know, in our infinite | ignorance we are all equal. -Karl Popper
