BTW: yet another thing that might help chasing the problem. It behaves in very deterministic way. I've built the firewire as module to be able to use the machine normally and I have found following behavior: (without X) kldload firewire (no problems) startx (interrupt storm) kldunload firewire (no problems) kldload firewire (interrupt storm) kill X (no problems) So it occurs deterministicaly when both firewire and X are loaded. Unloading any of them (or both of them ;-) ) helps. Petr ================================================================ Petr Holub CESNET z.s.p.o.
