Another idea: Do the disks spin up fast enough? Maybe the disks are not ready in time to be picked up by the first BIOS screen. Then when they spin up, they are detected by AHCI (which is hot-plug capable) just in time for loading Grub. Did you add any new hardware recently? I remember you wanted to install new disks. Maybe your power supply cannot take the load and this delays things. I've never seen this particular problem but this bootup-powerspike is the reason why large disk arrays typically start one disk after the other. > I copy my kernels by hand. Always have.

Did you use `cp -a`, maybe through an alias?
