I can confirm problems with DMA from IDE disks in -STABLE. The problems
seem to have been introduced in

        $Id: ide_pci.c,v 1.28.2.1 1999/07/20 22:58:20 julian Exp $

And the effect for me is that the system stops in singleuser mode, with
a "DMA failure" message. This is on a 440BX/PII-350 system.

Reverting to 1.28 (from 17. January 1999) fixes the problems.

Please back out 1.28.2.1, at least in -STABLE.
