[gentoo-user] [kernel 2.6.19-r4] DVD Drive extremely slow

Hey everybody!

I've upgraded to kernel 2.6.19 (gentoo sources) a few days ago however I 
can't get my DVD Drive working correctly.

I got an Dell Inspiron 9400 Royal. lspci tells me that I have an *ICH7* 
Chipset  [00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 
Family) Serial ATA Storage Controller IDE (rev 01)]

Here is all my relevant kernel configuration:

*Serial ATA (prod) and Parallel ATA (experimental) drivers*
<*> ATA device support
<*>   AHCI SATA support
<*>   Intel PIIX/ICH SATA support

*ATA/ATAPI/MFM/RLL support*
< > ATA/ATAPI/MFM/RLL support

*SCSI device support*
<*> SCSI disk support
<*> SCSI CDROM support
<*> SCSI generic support

*DMA Engine support*
[*] Support for DMA engines
[*] Network: TCP receive copy offload
< > Intel I/OAT DMA support

My SATA DVD Drive is configured as an *UDMA/33* Drive as dmesg | grep 
DMA tells me
...
ata2.00: ATAPI, max UDMA/33
ata2.00: configured for UDMA/33
...

Btw.: It worked perfectly well under openSUSE 10.2 (don't have it 
installed anymore, so I can't check which drivers were used) and gentoo 
kernel 2.6.18-r6 (I also used the ATA_PIIX driver there).

Any hints?

Cheers,
Jay

When you say you cant get it working correctly what exactly do you mean? Do you mean it's slow when reading or writing CDs/DVDs? Or do you mean you can't access it at all? What sort of methods did you use to test its speed?

AFAIK 33MB/s should be fine for a DVD drive - 16x is approx 21MB/s, *theoretically* so I doubt it will ever even reach that.

Hi, thanks for replying!

I get 2x DVD writing speed
I get  500KB/s to  1,5  MB/s  reading speed.

I can mount and access it, but it's just SLOW.

Any hints?

Cheers,
Jay

Hmm... I'm not sure to be honest. Nothing untoward popping up in dmesg? Have you tried various DVDR media?

Good point. Time to crack open hdparm maybe? Although dmesg did say the drive was using UDMA/33 but I'm not sure if that means Linux is actually using DMA for the drive or if thats just what the BIOS has it set at.

I'd maybe check IDE cables as well btw. I had a bad IDE cable once cause some fun problems with a hard disk.

Any good reason you've chosen to disable .../ATAPI/... support above?  

granted i don't have the same ide chipset but, other than that stuff,
here's what I would have enabled in my kernel if i were installing on
that system.

<*> ATA/ATAPI/MFM/RLL support
<*>   Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support
<*>     Include IDE/ATAPI CDROM support
<*>     generic/default IDE chipset support
[*]     PCI IDE chipset support
<*>       Generic PCI IDE Chipset Support
[*]       Generic PCI bus-master DMA support
[*]         Use PCI DMA by default when available

Thanks for your reply!

Yap. My DVD Drive is SATA.

good reason ; )  I guess i may not be much help to you, having
never owned or seen one of those.  Is if blue-ray or someting?  it's
neat that you don't have to waste space in your case on one of those
bulky ugly ancient-looking pata cables.  

however,i do wonder whether 
> ata2.00: ATAPI, max UDMA/33
> ata2.00: configured for UDMA/33
doesn't suggest that maybe ATAPI might be used as well by the
hardware?
