Ok I have done some research, and the above messages do come from the kernel, but may be transient errors, and not affecting this bug. The battery indicator showing full when it should show 75% does not always happen, but after a few suspend/resume cycles I can make it happen. When it does happen I can cat /sys/class/power_supply/battery/capacity and get the correct answer of 75. but both the value space /Hardware/Accessories/QPowerSource/DefaultBattery/Charge (which is what the battery indicator uses) and the QPowerSource::capacity() calls return 100, which is obviously wrong. This points to a bug in QtMoko (actually Qt Extended). It is odd because tracing the calls they ultimately just read /sys/class/power_supply/battery/capacity, so I suspect the QPowerSource service is dying or something like that. I'll continue to track this down, as it is quite a serious bug. I also got a dialog pop up saying the battery was critically low, when in fact it was at 75%. -- Jim Morris, http://blog.wolfman.com _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
