>Description:
I am unable to read a DVDs with a SONY DVD RW DRU-800A/KY01 on a JMicron 363 Controller. The system is a new Core 2 Duo system with an Asus P5B motherboard. I have tried two different Intel P965 chipset based boards with the same problem (Asus P5B Deluxe, Gigabyte DS3). I have tried 2 other DVD devices and an old 50x CD drive. I've replaced cables, tried the device on the controller by itself, and even tried a 3rd party PCI PATA IDE controller. None of the above fixes the problem.
A full dmesg output is available here:
http://pflog.net/dmesg
Without atapicam support, I can mount the drive but as soon as I try to copy a file from the DVD, I get the errors:
acd0: TIMEOUT - READ_BIG retrying (1 retry left)
acd0: TIMEOUT - READ_BIG retrying (1 retry left)
acd0: TIMEOUT - READ_BIG retrying (0 retry left)
acd0: TIMEOUT - READ_BIG retrying (0 retry left)
acd0: FAILURE - READ_BIG timed out
I am not able to dd the drive either (dd if=/dev/acd0 of=/dev/null bs=2048). I get the same errors. I was able to mount a CD disc and copy files, but I do get the same error for larger files on a couple of CDs. I am using a custom kernel config, but with only a few additions from GENERIC/SMP. And the same problem occurs with the GENERIC/SMP kernels. If I load atapicam, I see in dmesg:
ata4: reiniting channel ..
ata4: reset tp1 mask=03 ostat0=50 ostat1=51
ata4: stat0=0xd0 err=0xd0 lsb=0xd0 msb=0xd0
ata4: stat0=0xd0 err=0xd0 lsb=0xd0 msb=0xd0
ata4: stat0=0x50 err=0x01 lsb=0x00 msb=0x00
ata4: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb
ata4: reset tp2 stat0=50 stat1=00 devices=0x9<ATAPI_SLAVE,ATA_MASTER>
ata4: reinit done ..
Any attempt to mount/touch the device at this point hangs the process. Once it finishes, if I kldunload atapicam, I get:
atapicam0: detached

>How-To-Repeat:
Boot 6-STABLE from 9/8 or later on an Intel P965 chipset with a DVD/CD device plugged into the JMicron PATA controller. Attempt to mount the DVD and copy one of the larger .VOB files. Or simply boot and load atapicam, then try to mount a CD/DVD.
>Fix:
Not exactly a fix, but a workaround is to disable DMA. Obvious this limits the ability of the drive to play DVDs or burn CDs/DVDs.
