Greetings,
I am having problems with DMA access on my laptops drives. My research so far
indicates that this is likely to be an issue with the current state of ahci
development.
There are no BIOS options available for the IDE that are suggested in
workarounds.
Is there anything I can do to enable DMA for IDE drives, enable/disbale
options in the kernel?
Any help greatly appreciated.
Kind regards,
The laptop: ASUS W3030V.
Kernel: 2.6.12-gentoo-sources-r9
