** Description changed: + SRU justification: + On some hardware, calling pm-utils power.d scripts twice causes system crashes. + + Regression potential: + If I got this wrong, then in some cases users will have nothing processing power events at all, which may result in the system being left in "performance" mode while on battery. + Binary package hint: acpi-support acpi-support in lucid calls pm-powersave unconditionally on ACPI power events, but in lucid, upower is installed by default on the Ubuntu desktop and *also* calls pm-powersave, triggering on udev events. This results in running all the /usr/lib/pm-utils/power.d scripts twice, which is at best unnecessary and at worst, will confuse hardware by multiple calls to hdparm as in bug #340014. acpi-support should be fixed to skip calling pm-powersave in the presence of upower. (Since upower is unfortunately not yet part of the KDE stack, we will need to be selective at runtime rather than being able to prune this code entirely.)
