Hello, Apologies in advance if I sent this to the wrong place. I'm not sure where the kernel's boot-time device enumeration code lives. If this is the wrong forum, could someone please tell me the email address I should forward it to? Thanks. 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. 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 Can someone point me at the right forum, the code that needs to be modified, or better yet, fix the problem? I've never touched with the kernel code before. All help is appreciated. --Brian -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
