As error printout suggests there is a possibility that buffer underrun
protection is not effective in the recording mode in question. One can
argue if it's firmware deficiency or not, because if you read for
example Mt.Fuji drafts, buffer underrun protection is not defined [or is
optional] in DVD-R DAO mode. The exact wording is "If a buffer under-run
occurs, the logical unit shall stop writing immediately and the logical
unit shall start writing of Lead-out." Where "shall" is defined
previously in document as "mandatory requirement." This was discussed
once, long time ago...
Following option is most likely irrelevant, but such behaviour (INVALID
ADDRESS FOR WRITE while LONG WRITE IN PROGRESS) was observed under
Solaris 8 with USB connected units... You mentioned that you run Solaris
9, but is it external or IDE unit you're talking about?

You can double-check DMA settings and abstain from using your computer
during recording (in order to minimize probability of buffer underrun)
or you can download dvd+rw-tools at
http://fy.chalmers.se/~appro/linux/DVD+RW/. Despite the name and page
heading, it works with all kind of DVD media and runs under several OSes
including Solaris. A.
