Also, would it do any good to switch slots ? i already replied with the no-hlt suggestion, but still want to add... my system is actually very similar to yours in that i also have a kt133 chipseet, Nvidia videocard, SBLive card... i even run the same CCRMA kernel ;-) about irqs : irq 3 is *very* low priority so definately worth changing. i would try one of following: 1) see if you can change the irq in the bios. my bios allows to change certain irq's of pci slots and even onboard devices. 2) move the SBLive to another slot. if moving to another slot does not change the irq order after you boot linux, you might have to turn acpi off. you can boot with something like pci=biosirq or pci=noapic or acpi=off. i need that to avoid that linux reshuffles my 'perfect' bios irq settings. (i am at work now, this is from memory 8) good luck, let us know how you get along...
