I've been following along closely, trying to figure out why fixating cds 
hasn't been working.  Fortunately, this last patch has allowed cd 
writing to finally work.  It may have been fixed in the last patch for 
this kernel since I didn't try cdrecord directly with it, just 
graveman.   In any case, cd writing seems to be working wonderfully.  
Now the problem is dvd writing.  I'm apparently unable to even sense 
dvd-R's in the drive for writing.  Errors i'm getting from dvdrecord and 
such is the following (graveman just says it detects a CDR and it uses 
readcd)

This error occurs on every DVD-R I try, and I know it's not a disc 
problem because they burn fine in the other computer, and they used to 
work before libata.

I get no errors in dmesg, so I'm not sure what is going on here.   CD 
writing/reading works, dvd reading works but dvd writing (at least 
minus, i have no plus right now) doesn't.

If any further info is needed just ask.
