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. Mar 29 12:45:26 new-dw2 kernel: ata0 at port 0x3f6,0x1f0-0x1f7 irq 14 on isa0 Mar 29 12:45:26 new-dw2 kernel: ata1 at port 0x376,0x170-0x177 irq 15 on isa0 Mar 29 12:45:26 new-dw2 kernel: Interrupt storm detected on "irq14: ata0"; throttling interrupt source Mar 29 12:53:29 new-dw2 kernel: atapci0: <Intel ICH4 UDMA100 controller> port 0xf000-0xf00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 31.1 on pci0 Mar 29 12:53:29 new-dw2 kernel: ata0: channel #0 on atapci0 Mar 29 12:53:29 new-dw2 kernel: ata1: channel #1 on atapci0
