dma error on boot with cf card

dma error on boot with cf card

[Marc Donner]

hi,

i have a problem using a cf card with an ide adapter. 
using debian kernel 2.6.18-5 

on boot:

Feb  5 17:38:06 kernel: end_request: I/O error, dev hdd, sector 2000640


any ideas?

Adapter doesn't support DMA, but controller and CF cards do.  To fix,
tell the system NOT to use dma on that interface.

Most IDE to CF adapters fail to connect the DMA pins correctly since it
was a fairly (3 or 4 years ago) revision to the CF spec to support DMA
at all.

and how do i disable dma? it is the installer image, and no hdparm is 
availible. and the ide=nodma boot parameter seems not to work.

ide=nodma works for me on 2.6.18.  I think on newer kernels you need
hda=nodma which is nice since you can control it per device rather than
globally.
