But there is no problem with interrupt storm, glxgears are happy, and there is no excessive time spent in interrupts according to both top and 'systat -vmstat 1' (something beteen 0.1 to 0.4%). > can you try moving the graphics adapter to a different PCI slot? No. It's AGP Matrox G550 and there is the only AGP slot. Petr ================================================================ Petr Holub CESNET z.s.p.o.
