I recently added linux_base-fc4 on a host, to run linux setiathome enhanced versions (aka crunchers). The problem is that on multicore engines (core 2 duo, pentium D, etc...) where before there was 2 freebsd-crunchers on 2 differents core, now, with linux-crunchers, the 2 crunchers are sharing only 1 core. Can someone tell me what's wrong with this ? Have I missed something ? Is it an incompatibility from linux_base with smp hardware ? This problem seems to affects only freebsd 6.x, not the 7 branch. My kernels are all compiled with SMP support. I'm working for years with freebsd, but consider I'm really a newbee with linux. T.I.A. PM. PS: if you want to join us: http://boincstats.com/stats/team_graph.php?pr=sah&id=2119 (we have the 5th position in our country statistics; we are one of the oldiest team in our country; we tend to use mostly freebsd powered engines (56% freebsd today, 73% if you consider "Darwin" being a "freebsd").
