Hello people:

I have a question about version atapi-cam.c (rev 1.63.2.7.2.1) if reverting to rev 1.63.2.6.2.1 will fix the "INQUIRY ILLEGAL REQUEST" error.

Code: 
$ uname -srm
FreeBSD 8.2-RELEASE i386

atapi-cam.c revision:

Code: 
$ grep FBSDID /usr/src/sys/dev/ata/atapi-cam.c 
__FBSDID("$FreeBSD: src/sys/dev/ata/atapi-cam.c,v 1.63.2.7.2.1 2010/12/21 17:09:
25 kensmith Exp $");

The infamous error:

Code: 
$ dmesg | grep acd
acd0: DVDR <HL-DT-ST DVDRAM GSA-4120B/A102> at ata1-master UDMA33 
acd1: DVDROM <HL-DT-STDVD-ROM GDR8161B/0100> at ata1-slave UDMA33 
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01
acd1: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00


Thanks in advance.
 
By now, I don't try to compile the kernel with this change.

First I want to know if it works.

Someone had success with this fix?

Code: 
/usr/src
 
Code: 
cd sys/modules/ata && make && make install
or enable during kernel compile. The first method will build all ata modules that were not enabled during kernel compilation.

From /usr/src/sys/powerpc/conf/MYKERNEL

Code: 
# ATA and ATAPI devices
device		ata
device		atadisk		# ATA disk drives
device		atapicd		# ATAPI CDROM drives
#device		atapifd		# ATAPI floppy drives
#device		atapist		# ATAPI tape drives
http://www.freebsdwiki.com/index.php/K3b shows a working reference to atapi devices.
 
Well, I will post the results as soon as possible.

sossego, a lot of thanks for your time.
 
Without changes:

My kernel

Code: 
# ATA and ATAPI devices
device          ata
device          atadisk         # ATA disk drives
device          ataraid         # ATA RAID drives
device          atapicam        # SCSI emulation for ATAPI CDROM
device          atapicd         # ATAPI CDROM drives
device          atapifd         # ATAPI floppy drives
device          atapist         # ATAPI tape drives
options         ATA_STATIC_ID   # Static device numbering

# SCSI peripherals
device          scbus           # SCSI bus (required for SCSI)
device          ch              # SCSI media changers
device          da              # Direct Access (disks)
device          sa              # Sequential Access (tape etc)
device          cd              # CD
device          pass            # Passthrough device (direct SCSI access)
device          ses             # SCSI Environmental Services (and SAF-TE)


I can burn, mount or listen music from cd

But the error persists:

Code: 
$ dmesg | grep acd
acd0: DVDR <HL-DT-ST DVDRAM GSA-4120B/A102> at ata1-master UDMA33
acd1: DVDROM <HL-DT-STDVD-ROM GDR8161B/0100> at ata1-slave UDMA33
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01
acd1: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00


My conclusion:

I must compile atapi-cam.c rev 1.63.2.6.2.1, and cross my fingers. I hope I can remove those errors.
 
The error messages doesn't disappear, but anyway, is benign. The controller tries to send a command to the device. The device doesn't support it. That's all, everything else works.
