FreeBSD CVSUP'd on Thu Aug 30 22:03:24 PDT 2001, from cvsup7.

System config:
	1.3GHz Athlon, ASUS A7M266 motherboard
	512MB RAM
	60GB IBM 60GXP at primary master (UDMA100)
	Plextor 12/10/32A ATAPI CD-R/RW at secondary master (PIO)
	DVD-ROM <Pioneer DVD-ROM ATAPIModel DVD-116 0107> at secondary slave
		(PIO)

dmesg available upon request

	
>Description:

If you hit Ctrl-C to abort burncd, burncd leaves the CD-R/RW drive in an
unusable state: the disk cannot be ejected, and any further attempt at
using burncd results in (console) messages like:

	acd0: PREVENT_ALLOW - ILLEGAL REQUEST asc=2c ascq=00 error=04
	acd0: SET_SPEED - ILLEGAL REQUEST asc=2c ascq=00 error=04
	acd0: PREVENT_ALLOW - ILLEGAL REQUEST asc=2c ascq=00 error=04

Maybe the drive isn't unlocked when Ctrl-C is hit?????

(I was burning a cd-rw, and I didn't realize that the default speed is
"1".  I wanted to abort the process, erase the cd-rw, and retry.
Hitting Ctrl-C was a bad idea.  ;-)

	
>How-To-Repeat:

Start a burn using burncd and hit Ctrl-C after a moment or two.
