I've had cd burning problems since the stable NetBSD 1.4. My cd-r is a 
hp-7100 cdrw, connected to the secondary ide as the slave.

The only thing working is cdrecord, which is only able to burn a cd
with an image. After that for example, cdrdao is able to burn an audio
or 1:1 copy 65% of the time. Otherwise, if the recorder hasn't been
"initialized" with cdrecord, cdrdao won't work at all. Erasing a rw-disk
won't work at all anywhere.

After a boot the first cd to record gives cdrecord some difficulties,
and idles for some minutes before starting the actual burning. After the
first burnt cd, the following ones start to burn without the delay. This
all changes again, when the machine is rebooted.

The writer worked perfectly in 1.4, no delays, no problems. Since then 
I've tried numerous current-kernels, which all gave the same symptoms.
I even tried removing my cd-rom (the master in the secondary ide) and
made the burner the maste; still the exact same things happened.

Here is how the cdrecord and kernel act on the first burn:

This is what the kernel and cdrecord say when burning the next cd:

Then a question to to previous, why does the kernel choose pio mode 0
for cd1, even though it supports pio mode 3?



Can you cc the response to me, since I'm not on the mailing list. Thanks
