Problem: Linux seems to loose the battery information in recent kernels.
Keywords: Battery, ACPI, 2.6.14.x, 2.6.15
Description:
Since 2.6.14 I notice that after some time the Kernel seems
to loose the battery information via ACPI. This behaviour
is reproducable though I do not know how to provoke it (it
just happens). Occurs as well on the R52 from which are the
logs below as on my T41p. On LKML this problem seems also
to be mentioned by Narayan Desai and the same issues seems
to be reported by Alejandro Bonilla Beeche and Geoff Mishkin
mentioning this problem on other IBMs. As the latter uesed
some binary modules there was the request to reproduce it in
plain vanilla. I could provide this, including hopefully
something usefull below. It seems to be linked or the same
as
http://www.ussg.iu.edu/hypermail/linux/kernel/0511.0/2386.html
If further input is needed I'd happily provide it to get
sorted things out though I'll unfortunately not be able to
come up with a patch as this is far beyond my capabilities.

Me too with 2.6.15 on asus m6r. In 2.6.14 helped ec_burst=1 kernel parameter. I
will try few things with that and let you know (tomorrow or the day after).
It is broken since 2.6.14 times, IIRC 2.6.13 was OK.
I have also problems with irqs I found out yesterday. Don't know if it does have
sth. to do with this [acpi] problem (I mean LOC: 4394987, ERR: 891474, timer is
4394964).
regards,

Just to provide a data point, this is a biostar board and gkrellm
displays the cmos battery voltage as 3.14 volts right now, booted to
2.6.15.

I found that disabling CONFIG_PREEMPT fixed the problems for me. A
co-worker reported (today, coincidentally) that using the
acpi_serialize kernel option seems to have fixed the problem for him.

Please try patch http://bugzilla.kernel.org/show_bug.cgi?id=4588#c31
when PREEMPT enabled.
