Hi Hasso.  Thanks for working on the problem.

Here is our results from testing HEAD.

It definitely works a lot better than before.  We were able to write
to CDRW's and DVD's using cdrecord.  Burning a second disc also worked.
We did not get the interrupt storm like Steve did.

The tests were run on an Intel processor with a SiI 3512 SATA150 add on card.
Cdrecord-Clone 2.01.01a04

Even though it works, there were some error messages.

These are from dmesg.

   acd1: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00

Which all seem to have been generated at boot time.  Notice there was one 
pair of livelock limit messages, but that was it.

There were also some errors generated on the console when writing.

This is the first time we have even been able to boot up a machine on Dragonfly
with a SATA optical drive.  So this is a big step in the right direction :-).
I hope this information helps.
