Something changed in /sys output that caused HAL to think that there are two batteries: | The output of lshal shows that there are two UDI's with | info.capabilities = { 'battery' }: | | udi = '/org/freedesktop/Hal/devices/acpi_BAT0' | udi = '/org/freedesktop/Hal/devices/computer_power_supply_0' whether it's a HAL bug or a kernel bug, the original state should be restored and it should be worked out without breaking users of older HAL versions. grumble: way too many times do various system utilities break when i upgrade the kernel on my laptop. Maybe a new debug mechanism: we should start fingerprinting the exact /sys and /proc output and enforce that it's immutable across kernel releases as long as the hardware is unmodified?
