This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigBBD88453504D60DE655A043C Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable While trying to build math/atlas on a FreeBSD/amd64 9.0-CURRENT r212411, the kernel hangs at some point when math/atlas tries to run some tests (presumably the ones to profile the code and optimise). The kernel spouts messages about Starting event timers: LAPIC @ 1000Hz, HPET @ 127Hz; then LAPIC @ 1000Hz, HPET @ 8128Hz (iirc), back, then back again. After that, the system is no longer responsive, and eventually panic()s because some spinlock has been held too long in the pmap TLB invalidate code. Couldn't get a dump, because I had no dumpdev configured. Anyone else see this problem? I'm trying to reproduce it by building other ports (it has survived gcc44, gcc45, llvm and clang so far), but only math/atlas seems to trigger it. Cheers, --=20 Thomas E.
