Summary: hda intel | realtek alc262 | the system can't poweroff
Product: Drivers
Version: 2.5
KernelVersion: 2.6.29-rc1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Sound(ALSA)
AssignedTo: perex at perex.cz
ReportedBy: giovanni.pellerano at gmail.com
Latest working kernel version: 2.6.28
Earliest failing kernel version: 2.6.29-rc1
Distribution: Gentoo
Hardware Environment: Sony Vaio SR19XN
Problem Description:
After acpi button event, the system correctly goes for shutdown but at the end
it stops without poweroff.
I've filled a bug report [http://bugzilla.kernel.org/show_bug.cgi?id=12448] and
i thought that's was an acpi problem but doing a kernel bisect between 2.6.28
and 2.6.29 if found that the problem is in the commit:
1289e9e8b42f973f2ab39e5f4f2239ff826c27e9
Below you can find the output of the bisect, and in the kernel bug report 12488
you can find a lot of others information.
thanks for the attention.
here is the kernelk bisect output:
1289e9e8b42f973f2ab39e5f4f2239ff826c27e9 is first bad commit

ALSA: hda - Modularize HD-audio driver
Split the monolithc HD-audio driver into several pieces:
- snd-hda-intel HD-audio PCI controller driver; loaded via udev
- snd-hda-codec HD-audio codec bus driver
- snd-hda-codec-* Specific HD-audio codec drivers
When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
looks up the codec vendor ID and loads the corresponding codec module
automatically via request_module().
When built in a kernel, each codec drivers are statically hooked up
before probing the PCI.
This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
information for each driver, and driver-linking codes between
codec-bus and codec drivers.
TODO:
- Avoid EXPORT_SYMBOL*() when built-in kernel
- Restore __devinit appropriately depending on the condition
