Try as I might, I can't get k3b to burn data that resides on a

storage device on the fly. (ie a USB connected IDE hard drive)
I attain read speeds of 25MB/sec with this device when copying files
from the USB storage device. The CPU overhead associated with such
copies is about 3% on my machine.
Also K3B is exhibiting poor burning performance even when burning
from an image on the internal hard drive. The CDROMs are rated at
16x burning. I could only burn them at 8x without experiencing a
buffer underflow.
I burnt the same CDROMs at 16 or 24x last week with a different
kernel.
I'm running 2.6.9-1.649 smp today.
From the description, it sure sounds like the DMA for the cdwriter got
turned off somehow. What does hdparm say?
