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.
