It is continuing, using the external microphone the audio is too quiet no
matter how loud I set it with PulseAudio.
The audio onboard Lenovo W500 laptop is: Conexant CX20561 (Hermosa)
I have not had time to do any investigations to look at the git changes made.

As I indicated in the bugzilla, the problem arose after:
commit bf325f9538d8c89312be305b9779edbcb436af00
Author: Rafael J. Wysocki <[email protected]>
Date: Thu Nov 25 00:10:44 2010 +0100
ACPI / PM: Register power resource devices as soon as they are
needed
Depending on the organization of the ACPI namespace, power resource
device objects may generally be scanned after the "regular" device
objects that they are referred from through _PRn. This, in turn,
may cause acpi_bus_get_power_flags() to attempt to access them
through acpi_bus_init_power() before they are registered (and
initialized by acpi_power_driver). [This is not a theoretical
issue, it actually happens for one PnP device on my testbed HP
nx6325.]
To fix this problem, make acpi_bus_get_power_flags() attempt to
register power resource devices as soon as they have been found in
the _PRn output for any other devices.

I could build and run a 2.6.38 kernel with the above commit reverted.
It boots with no problem (with acpi support).
Today, I tested kernel from current linux-2.6 tree and the problem is
still there.
I don't have a clue where to start from to help debugging this.

Hi, Rafael.
I do not see the problem since that time.
Is it enough reason for closing it?

It is. Please reopen if you see it again.

Tried 2.6.39-rc4, still got segfault from aptitude update (but not
easily reproducible), updated bugzilla.
