(cat /proc/interrupts) If not, I believe this might be the problem and the solutions still eludes me (I don't think the problem lies in the IDE driver but in APIC support). I've 2 SiS based mainboards forced to use XT-PIC (SiS735 and SiS645 based) here but without this kind of problems (everything works until I start to add to many PCI cards in one system...). I'm willing to start hacking around (mostly on the 645 as the 735 is an always-on system). Is reading the arch/i386/kernel/*pic* files (and probably others) enough to start or is there somewhere else to look for information ?
