If you're burning audio CD's on Linux 2.4, be aware that DMA is only
supported for a block sizes that are multiples of 512 there, while
burning audio uses larger blocks (2352 bytes?).
How does burning data discs go? If that works fine, then this is
probably the problem.
"write error - loss of streaming" definitely is a buffer underrun
though, which matches the fact that enabling burnfree fixes the
problem.
