vaio preempt + acpi ac/battery trouble

[Greg Ingram]

Gentlemen,

On my Sony Vaio PCG-FXA32, I seem to have some trouble between ACPI and a
preemptible kernel.  The trouble generates messages about the time the
battery module loads.  We see a bunch of:

    ACPI-1133: *** Error: Method execution failed [\_SB_.PCI0.PIB_.EC0_._Q20] (Node cbeb6388), AE_AML_UNINITIALIZED_LOCAL

The real problem is that the AC Adaptor status is wrong.  The preempt
kernel always thinks the AC is off-line.

The only thing different in the configs is enabling preempt, though a diff
does show one other setting:

	# cd /usr/src/linux-2.6
	# diff production/.config preempt/.config
	97c97
	< # CONFIG_PREEMPT is not set
	---
	> CONFIG_PREEMPT=y
	119a120
	> CONFIG_HAVE_DEC_LOCK=y

I've tried to include only ACPI and power-related dmesg output below.
Full dmesg output is available here:

	http://www.symsys.com/~ingram/sony/production
	http://www.symsys.com/~ingram/sony/preempt

Any clues for better tracking down the problem?

Regards,

- Greg
