The emu10k1 share the same IRQ as the usb, and it is very bad. The emu10k1 must be on its own IRQ. You must check in the bios if you can assign the IRQ and/or move the card in another slot. You can also try to use the APIC interface in the kernel, but it will be better to get ride of this problem at the PIC level.
