DMA problem

DMA problem

[claude parisot]

  Hello !

Sorry to post a seconfd message on the list, I am only trying
to get an answern for this - it seems so - DMA-problem ??


I have some
problems with a brand new Plextor-drive, PX-W5224TA/T3B, I cannot
mount any CD or burn a CDR or CD-RW, except if I disable DMA with
following command :# hdparm -d0 /dev/hdd , a little bit annoying,
isn't it ?

If I insert a cdrom in the drive the led doesn't go out, it flashes
as usual but it stays green.

It seems to be a DMA-problem or a kernel-bug ???
Its only a supposition, I am a Linux-newbie, and I am looking
for an explanation and a solution ....

By mounting a cdrom I get following error messages :

Jan 11 20:46:00 ishwara kernel: scsi : aborting command due to timeout
: pid 102, scsi0, channel 0, id 1, lun 0 0x28 00 00 00 00 10 00 00 01 00

rive not ready for command

And then I have a freeze or at least a blocking of the sysem.
I have to reboot.

Could someone give me an explanation of what is happening and a way to
solve the problem .... is this a kernel-bug ? Or an incompatibility
between the motherboard and the drive ??

If you choose to help me, please don't be to esoteric, as I already
said, I am a newbie.

Please, could you Cc all answers to the adress :

Is it possible that your ide-cable can't handle the higher dma speeds
and makes errors? is it udma compatible? have you looked for a
firmware update for the burner @ www.plextor.com?

Firmware is up to date ....
I tried it with an other cable , UDMA 100 certified,
I tried all kind of things, putting the drive as master
but nothing has worked till yet.


Thanks for your answer

  also zu Deutsch - sprech' ich viel besser als Englisch.

Re: DMA problem

[Wes Janzen]

If those options don't work, you might try dropping down the dma mode by 
one.  I have a Maxtor drive that does something like that with my 
Promise PDC20269 when trying to use UDMA 2, but it works fine in UDMA 1.

Re: DMA problem

[DOSProfi]

There are many reasons for this Problem. Which Kernel Version are you running
(uname -a). Which distribution? SuSE, Debian, Mandrake, RedHat?

Re: DMA problem

[DOSProfi]

I don't know if this works, but I have found a new BIOS for that board:

http://www.asus.com.tw/support/download/item.aspx?ModelName=P4P800

In the notes are many "DMA"s inside.

DMA Problem

[Sanjay Bajaj]

I am having a setup issue with the DMA channel 0 with the DMA Controller 
on PPC440GX. The code I wrote is:

#if defined(CONFIG_PPC4xx_DMA)
    /* Setup the DMA */
    DPRINTK("PPC4xx pwidth: %d\n", ppc4xx_get_peripheral_width(DMA_CH0));
    ppc4xx_set_dma_mode(DMA_CH0, DMA_MODE_READ);
    ppc4xx_set_src_addr(DMA_CH0, (phys_addr_t)(pdev->x2mem_phys_addr + 
src_addr));
    ppc4xx_set_dst_addr(DMA_CH0, (phys_addr_t)dst_addr);
    ppc4xx_set_dma_count(DMA_CH0, count);
    ppc4xx_enable_dma(DMA_CH0);
    DPRINTK("PPC4xx DMA Status: %d\n", ppc4xx_get_dma_status());
#endif

The DMA never completes and leaves a residue of 'count'. What am I missing?

Please Help.
