Bug 58353

	Burning DVD+RW media using sysutils/dvd+rw-tools port
	(dvd+rw-tools-5.12.4.7.4_1) ends successfully if I try to burn a
	file 1500 bytes long:

	# growisofs -Z /dev/cd1 -r -J small.txt
	WARNING: /dev/cd1 already carries isofs!
	About to execute 'mkisofs -r -J /etc/make.conf | builtin_dd of=/dev/pass2 obs=32k seek=0'
	Total translation table size: 0
	Total rockridge attributes bytes: 250

	/dev/pass2: flushing cache
	/dev/pass2: stopping de-icing
	/dev/pass2: writing lead-out

	But if I try a large file (180MB) it doesn't burn:
	# growisofs -Z /dev/cd1 -r -J large.dat
	WARNING: /dev/cd1 already carries isofs!
	About to execute 'mkisofs -r -J sol-8-u5-ia-v2.iso | builtin_dd of=/dev/pass2 obs=32k seek=0'

	:-( write failed: Input/output error
	/dev/pass2: flushing cache
	/dev/pass2: stopping de-icing
	/dev/pass2: writing lead-out

	While doing that I get this in dmesg:

	DVD+RW Media that I'm burning is already fully formated:

	I haven't tried other types of DVD media (DVD-RW,DVD-R or DVD+R). 
	DVD+R and DVD-R media is too expensive to make a try, and I suspect
	it will not work as long as DVD+RW writing is not working.
	Burning DVD media with growisofs (sysutils/dvd+rwtools) worked
	before ATAng commit, so I conclude it's an ATAng bug, not a
	dvd+rw-tools bug.

Fix: 

None that I know of.
How-To-Repeat: 	try to burn DVD+RW media using growisofs (sysutils/dvd+rw-tools
	port)
