[Pkg-utopia-maintainers] Bug#727072: upower: continuously starting laptop-mode when on ac power

[Bin Guo]

Package: upower
Version: 0.9.22-1
Severity: important

Dear Maintainer,

With newly upgrade upower from 0.9.21-3 to 0.9.22-1, I noticed CPU usage
jumping up every several seconds after rebooting. Digging around, syslog
showed laptop-mode being continuously started when power plugged:

  This stopped when I unplugged power, and occurred when power cable
plugged in again.

  I downloaded upower_0.9.21-3 source, build and installed them. After
reboot, the problem disappeared.
