slow ide cdrom with via board and sata hd

Hello everyone

My problem is about a very slow cdrom transfer speed. Also the system is laggy while transfering data from cdrom. My PC consists of:
* asrock 939dual-sata2 s939 uli m1695
* sata hdd
* ide cdrom

As you can see hd speed is normal but cdrom is not.
I searched the internet but have no idea what to do. there is no possibility to tweak dma mode with hdparm but i think it should be activated by itself.

# hdparm -i /dev/dvd

 * signifies the current active mode

# hdparm -d /dev/dvd

/dev/dvd:

Any ideas?

Re: slow ide cdrom with via board and sata hd

So after reading more and more i discovered there are many people with a problem like this. They are talking about problems when switching to a newer kernel and new libata with it too.
some talk about "not loading ata_generic", ok i tried that, with no result.
afterwards someone came up with a modprobe parameter

modprobe pata_ali atapi_dma=1

. that worked a little bit. the system is finaly response while doing dvd I/O. but its not as fast as it should be...

# hdparm -tT /dev/dvd

/dev/dvd:
 Timing cached reads:   832 MB in  2.00 seconds = 415.70 MB/sec
 Timing buffered disk reads:    8 MB in  3.04 seconds =   2.63 MB/sec

I also tried to set UDMA fix in BIOS but my system doesn't care

Re: slow ide cdrom with via board and sata hd

i have the same motherboard and the same problem.
unfortunately, i tried to set atapi_dma=1 parameter and it works some time, but later it defaults to no dma (eg when writing a blank dvd the first 25% it's ok, at least 32x speed, and the rest 1-2x. after a reboot the same thing happens).

i tried other approaches and i found this: http://ubuntuforums.org/showthread.php?t=435706, that motherboard is different but the problem looks similar. i guess the libata module is loaded before the specific pata_ali driver and that's not right. i'll try to recompile the kernel in a few days and remove the libata module. maybe it'll work. i also tried booting with disablemodules=libata in grub (as stated in the mkinitcpio wiki page), but libata is loaded anyway and i cannot find a way to blacklist it (no, in rc.conf doesn't work because it's loaded before the initscripts by mkinitcpio)

anyway, if you come up with a different solution please post it.

Re: slow ide cdrom with via board and sata hd

Oh yes, I had a second look on that issue and also recognized a slowdown after some time.

About your second Idea, blacklisting libata. I think thats not possible because its automatic loaded when sata_uli or pata_ali is loaded, its a dependency. I already blacklisted ata_generic like its written in the link you posted but with no effekt on speed. ata_generic is not longer loaded for me but there is no effect.

# lsmod | grep ata
sata_uli                7300  6 
pata_ali               13060  0 
libata                171360  2 sata_uli,pata_ali
scsi_mod              113144  4 sg,sd_mod,sr_mod,libata
dock                   11168  1 libata

I will give your idea a try too, blacklisting libata... but... lets see

Edit:
Ok I tried this and its not working. I also switched sata/pata load order.

Conclusion for now: we are not with ata_generic or other not used drivers. There must be some other problem...

maybe some idea when looking at dmesg and the sata/pata related stuff? maybe some IRQ stuff i dont know of?

In gentoo there is a selfbuild kernel with no modules for sata pata stuff. Also its a lower version. Should I try to make my own arch kernel without modules for pata/sata? Or maybe downgrade kernel for testing?
I don't realy know any possible differences between modules and in kernel but maybe some little loadtime.

Re: slow ide cdrom with via board and sata hd

I managed it to work properbly with a custom Kernel that includes everything i needed in kernel, no modules.

CONFIG_SATA_ULI=y
CONFIG_BLK_DEV_ALI15X3=y

Hopefully the same works for you.
