Burning dao also failed for me with mid-April sources using burncd.
However, it produced this in the logs:

kernel: acd0: WRITE_BIG command timeout - resetting
kernel: ata1: resetting devices ..
kernel: done
kernel: acd0: write data underrun 9408/2352
kernel: acd0: write data underrun 9408/0
kernel: acd0: write data underrun 2352/0
kernel: acd0: write data underrun 2352/0
kernel: acd0: write data underrun 4704/0

4_STABLE can successfully burn in dao on the same system under the
same load, and CURRENT works on the same system with the same load
when not using dao.

I've updated my sources, but haven't tried again yet under no load
to see if fails similarly.
