I'm having some problems related to using cdrecord (mainly) and others program with deal directly with CDR/DVD-ROM. It's not a real problem, but I curious why this message is appearing:

bash-2.05$ cd1(ahc0:0:1:0): illegal request, data = 00 00 00 00 24 00 00 00 00 00
cd1(ahc0:0:1:0): illegal request, data = 00 00 00 00 21 00 00 00 00 00
cd1: dos partition I/O error
cd1(ahc0:0:1:0): illegal request, data = 00 00 00 00 24 00 00 00 00 00

The message in front of prompt is a kernel message. It overwrites anything on the screen. This message appears, i.e. when I use cdrecord to burn something. It looks like an error, but all CDs are burned normally. A detail is that the message only appears the first time I burn a CD. Subsequently usage of CDR are normal.

Running: NetBSD -current 1.6M, but occurs with the -release and others too

Thank you.
