: OK. Maybe I should test with that program as well. However,
: the name service for mersenne.org appears to be inoperational at
: the moment -- ns1.sbsi-net.com doesn't respond, and ns2.* replies
: with SERVFAIL. Bah!
Also see the thread in port-i386, "fftw_test failing on Core 2 Duo/GENERIC.MP"
which seems to be exhibiting the same symptoms.
I should probably try an unoptimised kernel one of these days to see if it's
some mis-optimisation or whether it's some other missing barrier or flushing
problem or some such.
