I see in the archives that other people have had problems like this, and that it's due to a BIOS problem. I've tried some of the patches that were sent in response, but it seems that those patches are already incorporated into the kernel I'm using (2.4.20-pre1-ac3) and I still have the problem. My kernel command line includes "ide0=dma". These lines show up on boot: PCI: Using IRQ router PIIX [8086/24c0] at 00:1f.0 PCI: Found IRQ 11 for device 00:1f.1 ...[several unrelated lines]...
