From b4154d4a01c6cc98b97dc239ca4302316c8f98da Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Sat, 1 Sep 2007 00:55:21 +0200 Subject: [PATCH] Fix sata_via write errors on PATA drive connected to VT6421 I think that I've found and fixed the problem. There is a copy/paste bug in vt6421_set_dma_mode() function which causes wrong values to be written to PATA_UDMA_TIMING register. This patch fixes a copy/paste bug that breaks DMA modes on VT6421 PATA port.
