I have an HP 8100 CD-Writer Plus (ATAPI) and I am trying to use it
with NetBSD 1.3.2 and cdrecord-1.6.1.
I try to burn a CD with
	cdrecord -v speed=2 dev=/dev/cd0d cdimage.raw
everything goes well until all the data has been written, then I get the
following output:

: Fixating
: 
: wdc0(1): lost interrupt
: 	type: atapi

:

The CD seems ok and I can read it on a different cd-rom drive.

BTW, it seems that cdrecord detects the CD-Writer Plus only after a boot.
After working for some time with X cdrecord reported a "Generic CD ROM"
and stopped.  After rebooting, cdrecord found the "mmc_cdr" again.

Thank you for your help,
