Re: DMA errors, then I/O errors, on 2.6.16

["Haar János" <djani22@netcenter.hu>]

Hi!

I am just a single user, but i have get this too earlier.

If it is a WD hdd, try to use master AND slave on the same cable, or try to
set "cable select" setting on hdd!

This works for me! ;-)

(Only WD made this for me, and only when it is a single master drive.)

Cheers,

Janos
