Subject: 2.6.23-rc8-mm1, -rc7-mm1 kill audio on HP nx6325

Hi,

This patch from Andi:

x86_64-mm-cpa-einval.patch

makes the hda_intel audio driver stop working on my HP nx6325.

The following line appears in dmesg (from 2.6.23-rc7-mm1:

ALSA /home/rafael/src/mm/linux-2.6.23-rc7-mm1/sound/pci/hda/hda_intel.c:1755: hd
a-intel: ioremap error

and the driver doesn't work afterwards.

Still, I'm not sure if the patch above is wrong or rather it exposes a problem
in the driver.

Greetings,
Rafael
