Public bug reported:
Hi,
Short summary:
system has sata disk:
[ 2.128771] ata3.00: ATA-8: Hitachi HDT721032SLA380, ST2OA31B, max UDMA/133
[ 2.128774] ata3.00: 625142448 sectors, multi 0: LBA48 NCQ (depth 31/32)
[ 2.129689] ata3.00: configured for UDMA/133
works fine:
sudo hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 4096 MB in 2.00 seconds = 2047.85 MB/sec
Timing buffered disk reads: 270 MB in 3.02 seconds = 89.48 MB/sec
and dvd drive:
[ 2.114207] ata4.00: ATAPI: HL-DT-ST DVDRAM GH41N, MN01, max UDMA/100, ATAPI
AN
[ 2.118545] ata4.00: configured for UDMA/100
sudo hdparm -tT /dev/sda
/dev/sr0:
Timing cached reads: 450 MB in 2.00 seconds = 225.00 MB/sec
Timing buffered disk reads: 4 MB in 3.23 seconds = 1.24 MB/sec
k3b burns very slowly: 0.11x speed instead of 4x (as media allows).
$ hdparm -i /dev/sr0
/dev/sr0:
Model=HL-DT-ST, FwRev=MN01, SerialNo=K5Y9AP52302

DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=no
Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7

$ sudo hdparm -I /dev/sr0
/dev/sr0:
ATAPI CD-ROM, with removable media
Model Number: HL-DT-ST DVDRAM GH41N
Serial Number: K5Y9AP52302
Firmware Revision: MN01
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions,
SATA Rev 2.5, SATA Rev 2.6
Standards:
Likely used CD-ROM ATAPI-1
Configuration:
DRQ response: 50us.
Packet size: 12 bytes
cache/buffer size = unknown
Capabilities:
LBA, IORDY(can be disabled)
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns
seems like dma is not set for dvd drive, but dmesg claims dvd drive
configured ok for dma:

I've rebuild the kernel in order to put all libata into loadable modules and
blacklisted ata_generic
lsmod|grep ata
pata_amd 14628 0
pata_acpi 5312 0
pata_atiixp 6048 0
libata 201068 4 pata_amd,pata_acpi,ahci,pata_atiixp
It didn't help in improving dvd burning speed.
Happy New Year!
Thanks,
