One of those came from me. Its better than what I've had before. I've
tinkered a bit, with and without debugging and ide-scsi, and I still
managed to get it to blow up. But I no longer see the insane loads
I've had on earlier kernels.

Attached is the output from a sesison with copying from CDs to the USB
drive with no ide-scsi, and i've put a comment it where it seems to
fall over:
