Additional info:

the following error message is in /var/log/messages:

Nov 11 22:44:37 minio kernel:     ACPI-0508: *** Error: Method execution failed [\_SB_.PCI0.LPC_.EC__.BAT0._BIF] (Node df586580), AE_AML_METHOD_LIMIT

The new message is appended every time /proc/acpi/battery/BAT0/info is accessed

The first ACPI error is this one:

Nov 11 20:37:58 minio kernel:	  ACPI-0292: *** Error: Looking up [SERN] in
Nov 11 20:37:58 minio kernel:	  ACPI-0508: *** Error: Method execution failed
[\_SB_.PCI0.LPC_.EC__.GBIF] (Node df5866c0), AE_ALREADY_EXISTS

There are no 3rd party modules in the kernel (only the ipw2200 firmware).

I'm having the same issue on my T40p 2373-G3U.  Same messages printed by this
kernel as the previous reporters.  I've had similar issues with 2.6.13 as well,
but hadn't had time to report it into bugzilla.  The messages were more of the
"Looking up [SERN] .. AE_ALREADY_EXISTS" and similar messages.

kernel-2.6.12-1.1456_FC4  Appears to work fine.
kernel-2.6.13-1.1526_FC4  Fails intermittantly.
kernel-2.6.13-1.1532_FC4  Fails intermittantly.
kernel-2.6.14-1.1637_FC4  Fails quickly, stays failed.

Same issue on IBM R40.

Is this a duplicate of bug 172915?
