It seems that drm interrupts are routed to firewire device by APIC (the machine is dual-processor box). Here's fragment form 'systat -vmstat 1': Interrupts 74331 total 1: atkb 6: fdc0 128 8: rtc 12: psm 13: npx 14: ata 15: ata 72290 16: fwo 140 17: pcm 99 18: bkt 676 20: em0 998 0: clk However there is nothing shown for drm0 which has allocated irq 11 (as shown in dmesg). dmesg output is below my signature. Is there any workaround/patch for this? Thanks, Petr ================================================================ Petr Holub CESNET z.s.p.o.
