Doesn't shed any light on the rest of it. What >happens if you boot with irqpoll enabled ? (wondering if the timeouts are >ACPI or IRQ routing stuff) I rebuilt the kernel; the DVD and USB devices are functional now. I'm not sure what the problem was before. On a side note: In 2.6.24.rc1 the DVD starts working right away, but on a SLES10_SP1 kernel, it takes some time for it to step down to a PIO mode before the DVD can be mounted. Oh well. Thanks!
