Bug#436992: linux-image-2.6.18-4-amd64: sb600

Package: linux-image-2.6.18-4-amd64
Version: 2.6.18.dfsg.1-12
severity: medium

Booting this kernel on a machine equipped with 4GB+ RAM and sb600-based
controller, causes ahci to hang, as the hardware is not really 64 bit

Since 2.6.22 there exists a patch already, details can be found on LKML
("ahci: disable 64bit dma on sb600") Here is as web-archive link of the
thread http://www.mail-archive.com/linux-ide@vger.kernel.org/msg06695.html

I would love to see that patch backported and appear in the
etch/proposed updates.

Meanwhile, there is a workaround: Set mem=4095M on the append line, but
you cannot use much more than 3.3GB of the 4GB then.
