> In other words, the problem is with the firewire hardware or driver. Why? I don't see why the problem couldn't be in drm as well... :-( N.b. that firewire without X running works fine, no interrupt storms at all. After what's shown below I'd say that drm0 is responsible for problems as it allocates irq 11 with ACPI but irq 16 without ACPI. > BTW, have you tried without ACPI? Yep---right now :o). drm0: <Matrox G550 (AGP)> mem 0xfd000000-0xfd7fffff,0xfdefc000-0xfdefffff,0xf800 0000-0xf9ffffff irq 16 at device 0.0 on pci1 info: [drm] AGP at 0xf0000000 128MB info: [drm] Initialized mga 3.1.0 20021029 on minor 0 drm0: [MPSAFE] -su-2.05b# vmstat -i interrupt total rate irq1: atkbd0 232 1 irq6: fdc0 4 0 irq8: rtc 26063 127 irq12: psm0 510 2 irq13: npx0 1 0 stray irq13 1 0 irq14: ata0 2622 12 irq15: ata1 30 0 irq16: drm0 4488 21 irq17: pcm0 1 0 irq20: em0 388 1 irq0: clk 20361 99 Total 54701 266 => so w/o ACPI the drm0 occupies irq 16 instead of 11. Now I can't see hyperthreaded processors without ACPI. I've checked to load firewire module and X with DRI and it works fine together when no ACPI is present! BTW: I've checked whether hyperthreading can be to blame and it seems to have no effect. When I run the machine with ACPI on and hyperthreading off, the drm0 allocates irq 11 and I can't see it in 'vmstat -i' any more again. dmesg output of machine without ACPI is below my signature.
