Bug Description
Binary package hint: gnome-power-manager
In the latest Ubuntu release, Intrepid Ibex, the Gnome Power Manager has a tedency to hang for a very long time when it enters the function "do_nanosleep" (as reported by Intel Powertop), showing generally unstable behavior. Moreover, gnome-power-manager also hangs when a battery is plugged in or out. Ironically, Powertop also notes that gnome-power-manager is the leading cause of battery life reducing interrupts when gnome-power-manager hangs itself. Solving the hang may therefore also help my battery life.
Researching the problem on the internet, it seems this bug may be in the kernel, fixed by a patch to ACPI EC subsystem. This thread seems to indicate that these timer problems were solved in the latest kernel iteration. (http://
Gnome-Do, which also seems to sometimes enter do_nanosleep has a similar hanging problem, so that also might be related.
I am using the latest Ubuntu release, Intrepid Ibex, with all the latest updates installed.
UPDATE: It turns out that disabling display dimming seems to fix these problems. Even though the display is now set not to dim, it dims anyway, but at least the Power Manager no longer freezes.
