Re: [issue1158] Problems with a SATA DVD burner

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    I picked up a HP SATA DVD Writer today to play and so far it has worked
    flawlessly with the latest HEAD.  I was able to format and write DVD-RW's,
    and rewrite them half a dozen times without error.  I put in a DVD-R and
    burned it (with dfly.iso) no problem.  I put in a second DVD-R and burned
    IT no problem too.

    I did get a bunch of transient errors from boot and from cdrecord trying
    various types of commands, but it didn't stop it from burning the DVD.

    On boot:

acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 
Mounting root from ufs:/dev/ad6s1a
cd0 at ata2 bus 0 target 0 lun 0
cd0: <HP DVD Writer 1070r RH22> Removable CD-ROM SCSI-0 device 
cd0: 3.300MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed

    The transient errors from burning the DVD-RW:

acd0: FAILURE - READ_BUFFER ILLEGAL REQUEST asc=0x24 ascq=0x00 
acd0: FAILURE - READ_TOC ILLEGAL REQUEST asc=0x30 ascq=0x02

    The transient errors from burning the DVD-R:

acd0: FAILURE - READ_BUFFER ILLEGAL REQUEST asc=0x24 ascq=0x00
