i bought new CD-RW. older was SCSI (but refused to record any CD-RW
since 1/2 year thats the reason i bought new) new is IDE.

cd1 at atapibus0 drive 0: <HL-DT-ST GCE-8520B, , 1.00> cdrom removable
cd1: 32-bit data port
cd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
cd1(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA
data transfers)

the question is - is it normal so huge CPU load? older was using about
5% with 4x speed. this can't record over 16x without underrun. at 12* it
uses about 60% CPU while more are system than user.

is IDE so bad in that case? it is using Ultra/33 mode, same as hard drive
which is able to give 16MB/s

PS will mount rainier be supported? how true is that it means that it just
accept write same as disks (just by sector number)?
