Summary: Device enumeration at boot doesn't detect acpi
battery.
Product: ACPI
Version: 2.5
Kernel Version: 2.6.32-22-generic #33-Ubuntu SMP x86_64
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: acpi_power-batt...@kernel-bugs.osdl.org
ReportedBy: bhut_o...@yahoo.com
CC: rui.zh...@intel.com
Regression: No
I have a laptop running Linux 2.6.32-22-generic #33-Ubuntu SMP x86_64. My
laptop is an ACER Aspire 6930. When I boot, the battery isn't enumerated into
"sysfs" like gnome-power-manager expects it to be.
After boot, the following command finds nothing:
% find /sys -name "BAT1" -print
If I inspect the contents of one of the files in the /proc/acpi/battery/BAT1
directory, they'll appear:
% cat /proc/acpi/battery/BAT1/state
present: yes
capacity state: ok
charging state: charged
present rate: 0 mA
remaining
capacity: 3619 mAh
present voltage: 12131 mV
% find /sys -name "BAT1" -print
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT1
/sys/class/power_supply/BAT1
This is repeatable on every boot. Once I "cat /proc/acpi/battery/BAT1/state",
gnome-power-manager recognizes my battery (via upowerd) and all is well.
This is the non-"gnome-power-manager" part of
https://bugzilla.gnome.org/show_bug.cgi?id=617529
[I'll attach acpidump and dmesg output soon. Must reboot first.]
