Can you show full 'dmesg' output, including (a) everything from boot and 
(b) an attempt to burn a CD with cdrecord and (c) an attempt to burn a 
DVD with growisofs

Full lspci would also be nice (I don't think the above is all of it, is it?)

If you want to collect stupid amounts of [quite helpful] debug output, 
you may s/undef/define/ on the following lines of include/linux/libata.h 
in the kernel:

#undef ATA_DEBUG                /* debugging output */
#undef ATA_VERBOSE_DEBUG        /* yet more debugging output */

If you are seeing error messages, this helps understand them:
