Title: How-to Disable DMA on IDE compactflash disk
Post by: brianez21 on May 17, 2010, 07:23:36 PM

Hi,

I am running TinyCore Linux from an 8GB Kingston Compact Flash card and I noticed it is booting very slowly due to the kernel's DMA driver trying and failing to enable DMA on my IDE adapter.

What is the correct kernel boot option to disable DMA? I already tried libata.force=1:pio4 but that had no effect.

Thanks in advance!

Did you try nodma?

Yes I tried that cheatcode (nodma and ide=nodma) and it had no effect. Thanks for suggesting it though.

//EDIT// I found an argument that does it! Just append ide_core.nodma=0.0 to the end of your kernel options.
