custom _BST method

Please
1. build a kernel, later than 2.6.34, set CONFIG_ACPI_DEBUG.
2. reboot with acpi.debug_layer=0x80, acpi.debug_level=0x06.
3. mount debugfs to /sys/kernel/debug
4. download this _BST.aml file
5. apply this custom _BST control method by running "cat _BST.aml > /sys/kernel/debug/acpi/custom_method"
6. run "grep . /proc/acpi/battery/*/*"
7. attach the dmesg output after this test.

There's a workaround, but i'd like to see code that solves definetively our problem.
Comment 21 AceLan Kao 2010-07-13 06:14:43 UTC
There is a workable patch here[1] and confirmed by Ubuntu user that the patch works correctly[2].
I'm trying to contact the patch owner now and I think I should expose it here to see if this patch is acceptable.

News about inclusion in main tree/creation of a new patch?
Comment 23 Alex 2010-09-06 16:49:55 UTC
Solution is TimelineX-ACPI-fix.patch in kernel. I tested it on Acer 5820t, Ubuntu 10.04 with trevinos precompiled kernel 2.6.35 with this patch its working.

patch: http://download.tuxfamily.org/3v1deb/acer-timelinex/

5 weeks old solution and status still NEEDINFO
<OMG> fix it in oficial kernel </OMG>
