Just finished installing Gentoo (again) from stage2. When I hdparm on my hard disk, I get this error.
setting 32-bit I/O support flag to 3
setting multcount to 16
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
I assume this must be something with my kernel config, but I have no idea - I never changed (as far as I know) anything to do with DMA in the config.
