Well.. Yes, there is some interrupt sharing. Relevant parts of dmsg: [ltning@carnen] ~$ dmesg | grep "irq 2" IOAPIC #0 intpin 19 -> irq 2 uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0xd400-0xd41f irq 2 at device 4.2 on pci0 ahc0: <Adaptec aic7890/91 Ultra2 SCSI adapter> port 0xd000-0xd0ff mem 0xe2000000-0xe2000fff irq 2 at device 6.0 on pci0 amr0: <LSILogic MegaRAID> mem 0xe3000000-0xe300ffff irq 2 at device 9.1 on pci0 I don't like the fact that the LSI and the Adaptec are sharing IRQs, given that the LSI is the main system drive controller (which is why I don't use the Adaptec at all - and it cannot be disabled in BIOS I think!)... I should perhaps try to reallocate some of the IRQs, but I don't really have a clue how to do that, since I have no VGA in that box.. Ohwell, I guess I just have to rip it open ;) Any other clues? Thanks, /Eirik
