[kde-linux] K3B won't burn right?

My guess is that burning is a more resource intensive and time sensitive 
thing than reading. So a PC with slightly marginal hardware components 
might be able to handle reading with no problems, but start to stumble 
when burning. The kernel appears to be monitoring such things, and maybe 
takes protective action when it detects increased failures on the 
DMA/IDE/SATA bus. Perhaps one of those protective actions is to turn off 
DMA, or whatever other bus feature that might be triggering problems.

Also wonder what speed the device bus is running at. On all of my 
systems, I've never budged from the default 33MHz, even on machines that 
had 66MHz bus speeds. Does that make a difference?

Also, burning involves the drive's hardware in a way different from 
reading - any burn protection feature it might have. Perhaps there's 
something going on connected with that?

I don't know, my limited hardware geekery was long ago when busses and 
timing issues were much more challenging. Burning CDs used to produce a 
lot of coasters, even with hardware and media that were nominally good.

Just WAGging around here.
