Maybe. Yesterday's patch seems to work (with limit to 60°C), though... It
sets the CPU limit to 60°C.

I think the reducing of the cpu clock have to be done only on
emergencies: when the temperature is over an
Do you mean it did crash with the last patch (or not?) ?
Yup!
If yes, I'll put the limits quite high on the chip (Say 65°C), and start
the fan as it is now (Slow at 50, fast at 58).
That ist what I'd suggest though I don't understand the underlying
mechanism.

Ok. On my Albook 15 1.25GHz:
fan_speed=128 returns 2070
fan_speed=255 returns 2800

Hi,
Unfortunately I still have the same problem: with fan powered on
continuously for about 4 minutes the computer powers off
Can you send the contents of

/sys/devices/temperatures/cpu_limit
/sys/devices/temperatures/gpu_temperature
Hi,
After cooling under 47 centigrade, the fan switches off again. But if I
try to create higher cpu-load using something like
while (true); do for i in cpu_limit cpu_temperature fan_speed; do cat
$i; echo; done; done
the machine switches off when cpu_temperature reaches 56 centigrades.
while (true); do for i in cpu_limit cpu_temperature fan_speed; \
do cat $i; echo; done; done
By the way. This hammers on the chip, you should add a sleep 1 to your
inner loop.

ok, thanks. Does it happen when you specify fan_speed=XXX ? (try 128)
Specifying fan speed puts the fan control under manual mode, maybe it
could prevent the chip from

Hi people,
could the ones here with Albooks and an ADT7460 chip for the fans try this
patch and tell whether it works fine or not ?
to test:
. apply the patch against latest BenH's tree
. define CONFIG_THERM_IBOOKG4 to m (select module in

It seems that it doesn't apply to latest (rsynced 1 minute ago) BenH's

Ok, now it seems to work but after 2 or 3 minutes with the fan powered
on (limit_decrease=10) my powerbook power off without any reason.
I don't think this could be a driver problem but it happened to me
twice in my tests.
Maybe this is due to an error from me - I swapped two registers
