2.6.12-rc1-mm[1-3]: ACPI battery monitor does not work

2.6.12-rc1-mm[1-3]: ACPI battery monitor does not work

[Rafael J. Wysocki]

Hi,

There is a problem on my box (Asus L5D, x86-64 kernel) with the ACPI battery
driver in the 2.6.12-rc1-mm[1-3] kernels.  Namely, the battery monitor that
I use (the kpowersave applet from SUSE 9.2) is no longer able to report the
battery status (ie how much % it is loaded).  It can only check if the AC power
is connected (if it is connected, kpowersave behaves as though there was
no battery in the box, and if it is not connected, kpowersave always shows
that the battery is 1% loaded).

Also, there are big latencies on loading and accessing the battery module, but
the module loads successfully and there's nothing suspicious in dmesg.

Please let me know if you need any additional information.

Greets,
Rafael

Could you just revert ec-mode patch, then retest?

I assume you mean the "Enable EC Burst Mode" patch at:

http://linux-acpi.bkbits.net:8080/to-akpm/cset%401.2181.17.12?nav=index.html|ChangeSet@-2w

Anyway, reverting this patch helps. :-)

Greets,
Rafael

They are available at:

http://www.sisk.pl/kernel/050401/dmesg.out
http://www.sisk.pl/kernel/050401/dsdt

The dmesg output is from 2.6.12-rc1-mm4 with the patch reverted.

Rafael

Are these problems still present in 2.6.12-rc5 or 2.6.12-rc5-mm1?

2.6.12-rc5 is unaffected, as it does not contain the patch that causes
the problem to appear.

The problem is still present in 2.6.12-rc5-mm1.  I have created a bugzilla entry
for it at http://bugzilla.kernel.org/show_bug.cgi?id=4665
