I am using cdrecord for CDRs and growisofs for DVDRs on my

===> lars@laphroaig:~ %dmesg | grep cd
cd0 at atapibus0 drive 0: <HL-DT-ST DVDRAM GSA-4081B, K2I41CG5459, A100> cdrom 
removable
cd0: 32-bit data port
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
cd0(jmide1:0:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA)

running NetBSD/amd64 -current. It usually works fine. 

I have however been able to lock the machine solidly when writing both 
CDRWs and DVDR/DVDRWs. I am still trying to understand why (interrupt 
issue? even mouse pointer stalls in X), but I think it is a separate
problem. This behaviour started a couple of weeks ago.
