HP Compaq 6710b here. Fan allways worked well... until I upgraded to
Karmic. Now, if I resume from suspen, the fan goes to chainsaw fullspeed
mode.
The workaround above - heating both cpus, in my case I start this script
here twice (for each core):
#!/bin/sh
while true; do i=$(( i + 1 ); done
I noticed that reloading module named 'thermal' usually helps. I even
made cron entry that does rmmod thermal; modprobe thermal every five
minutes or so.
Now that i have stock 9.04 kernel, thermal is not compiled as module and
i came to look for solution.

FYI: The script 99funguj in Ubuntu bug #77370 implements a simpler (and
quicker) workaround that doesn't require heating the CPU until a trip point is
reached.
However, one still needs to enable polling so that the fan keeps reacting to
changes in CPU temperature after resuming from standby, ev
Donatello, your method is flawed, as the trip_points don't get updated
anymore on trip events even if temperature polling is set on. This
results in the temperature bouncing around a static trip point causing
the fans to turn on and off way too often.

You must set the polling frequency at startup. I forgotten that.
echo -n 5 > /proc/acpi/thermal_zone/CPUZ/polling_frequency
So how the workaround works.
The PC resumes with fan at full speed but /proc/acpi/fan/FAN? are set to
off. It is impossible to stop the fan because Linux thinks the fan is

The problem persists with Ubuntu 9.04 Jaunty Jackalope; I have the same
HP 6735s (default install, but running the proprietary ATI fglrx
driver). Found no working workaround except reboot yet; heated the
notebook to 71*C, but fan kept spinning fast.

Suspend works just fine with Windows XP/Vista. I've been trying around
with Intrepid (Ubuntu/Kubuntu) and Ubuntu Hardy and all of these
experience the problem. Currently,

2.6.24-23-generic
For me, this workaround has not worked. After suspend resume the fan
states are set to 3. My only
