Well, that's not good. Can you translate that address to a line of
code?

Besides that, can you enable DYNAMIC_DEBUG in the config and append
'dw_dmac_core.dyndbg dw_dmac.dyndbg' to the kernel cmdline?

Enabling debug messages in the sata_dwc driver might also be informative.

Changed the sata-dwc to a module .

That's strange. The only way that can happen is if
dmaengine_prep_slave_sg() return NULL, and that really shouldn't be
happening. Did you turn on debug messages in dw_dma? You can enable
some extra debug messages by adding "#define VERBOSE_DEBUG" at the top
of drivers/dma/dw/core.c

Could you post the entire kernel log? There might be important
information before the errors start.

This log is weird. The sata_dwc_probe() function prints several things
(one using dev_notice()), for instance this:

/* Read the ID and Version Registers */
idr = in_le32(&hsdev->sata_dwc_regs->idr);
versionr = in_le32(&hsdev->sata_dwc_regs->versionr);
dev_notice(&ofdev->dev, "id %d, controller version %c.%c%c\n",
idr, ver[0], ver[1], ver[2]);

The dw_dma_probe() function also prints a line:

dev_info(chip->dev, "DesignWare DMA Controller, %d channels\n",
pdata->nr_channels);

These messages are nowhere to be seen in your log, nor are numerous
others that really must appear before before sata_dwc_qc_prep_by_tag()
can be called.

It would be better to add 'ignore_loglevel' to the cmdline as well.

I'd like to note that the driver works on my Sigma Designs based system
using a different DMA controller, so it's not completely broken. The
DMA driver could still be faulty, but that still doesn't explain the
missing kernel messages.
