Bug#255425: kernel-source-2.4.26: Patch to enable Dell PowerEdge 750 SATA DMA support
Package: kernel-source-2.4.26
Version: 2.4.26-2
Severity: wishlist
Tags: patch
This patch by Nick Craig-Wood enables DMA support for the Intel 6300ESB
SATA disk controller in the Dell PowerEdge 750. A compatible driver is
already in the kernel, so this patch just adds the new PCI device id.
