The machine has a 3ware card in it, so we had the IDE controllers disabled in the BIOS. However, on bootup Mar 29 12:45:26 new-dw2 kernel: Interrupt storm detected on "irq14: ata0"; throttling interrupt source We rebooted to the BIOS, enabled the IDE controllers, and all was happy again. With it "disabled" in the BIOS, it shows up as an ISA device ? Here is the before and after.
