[Bug 632197] [NEW] lm-sensors limits and calculations aren't retained after waking from sleep

[Launchpad Bug Tracker]

I'm running 10.04 x64, with btrfs / and ext2 /boot. All packages are
current from Synaptic.

I have a custom sensors.conf file in /etc/sensors.d, with set x_min and
set x_max values that are read when init starts /etc/init.d/lm-sensors
via sensors -s. The motherboard in question is an Asus M3N78-EM, with an
Athlon X2 4850e, 4 GB of RAM, onboard GeForce 8300 IGP, and no add-on
PCI cards. The custom sensors.d file is for the it8712-isa-0290 chip,
from the it87 kernel module, and replicates the limits from the
asus_atk0110 kernel module. (I use the it87 module because it has fan
PWM control, and the asus_atk0110 doesn't.) To allow it87 to load, I've
passed acpi_enforce_resources=lax on my kernel boot line.

After a normal boot, running "sensors" from a shell window shows the
limits in question, with the appropriate calculations for the +5V and
+12V lines.

The it87 module survives sleeping and waking, but running "sensors" from
a shell window after waking shows the default limits and all
calculations are gone. Running "sudo sensors -s" manually restores
these. To prevent this behavior, I had to drop a script in
/etc/pm/sleep.d to run "sensors -s" on thaw.
