>Description:
	LG S-SATA DVD-Writer <HL-DT-ST DVDRAM GH20NS10/EL00> is attached to a 
	'PDC40718-GP SATA 300 TX4 Controller'. 

	noticeable: The hard drives are connected to channel 1 and 2 
		    on the controller board, the DVD is conencted to channel 3
	            (also tested on ch4).
		The kernel detects two harddrives as channel 2+3 (counted from 0) i
		and the DVD on chanel 0 (first channel). On BIOS 

	Before the DVD is detected there are some ATA timeout / PACKET errors:
	acd0: timeout waiting to issue command
	acd0: error issuing ATA PACKET command
	acd0: timeout waiting to issue command
	acd0: error issuing ATA PACKET command
	acd0: timeout waiting to issue command
	acd0: error issuing ATA PACKET command
	acd0: CDROM <HL-DT-ST DVDRAM GH20NS10/EL00> at ata2-master SATA150
	acd0: timeout waiting to issue command
	acd0: error issuing ATA PACKET command
	[... forever ...]

	* I also tried to connect the DVD to the onboard-prmise
	atapci1: Promise PDC20376 SATA150 controller ... on pci2
	without success. 

	* I tried some other SATA-Cables.
	* I measured +12V and +5V from a 5.14" power plug parallel to the DVD 

	* I was lucky to boot one time with the DVD attached to the Promise 300 
	  by opening / ejecting while these ATA-timeouts on acd0. 
          # dd if=/dev/acd0 of=/dev/null bs=2k count=1  on console
          resulted in 3x timeout+error from kernel followed by the i/o error message 
	  from dd followed by 2 more timeout+error lines of the Kernel
	* The two hard drives ad6 and ad10 are doing fine and without any 
	  error messages, ad6 is a geli device which would thow error-messages 
	  on corrupted data.

	If there is something else I may test or information I have to provide 
	please ask soon. I'm willing to update to 6-STABLE or 7.0-RELEASE or 
	7-STABLE if this would be a solution.


>How-To-Repeat:
	attaching the DVD to the promise300
