Package: laptop-mode-tools
Version: 1.45-1
Severity: grave
After doing a resume from suspend the laptop-mode settings that affect
the hard disk power management are not applied. On a fresh start
everything is perfect, but after a resume from hibernation, if the fans
don't spin, I can hear small clic sounds from the hdd (presumably). They
are perfectly correlated with the increase of the "193 Load_Cycle_Count"
value in the smartcl status. The load/unload cycles are extremely
frequent, more than 200 per hour.
Marking it as grave, it can shorten the life of the hdd a lot. In the
extreme case of 200 cycles per hour I would be left with 600000 / 200 =
3000 expected hours of functioning, less than a year.
Doing a "/etc/init.d/laptop-mode restart" instantly solves the clicking.
Running Debian Unstable, updated recently.
