** Description changed:
I have Feisty installed on my ASUS laptop, model A3500G (or A3000 or
A3G, I think). It has a Intel Pentium M 1.6 GHz processor, with
frequency going from 600 MHz to 1.6GHz by steps of 200 MHz. My kernel is
2.6.20-15-generic
The cpu fan can run in different speeds, 3 I think. The problem is that
when it reaches the highest speed, it never slows down or turn off, it's
very annoying.
Steps to reproduce:
- turn on the laptop
- make the temperature go high for the fan to start (e.g.: play xmoto ;-) )
- that's it, the fan is at the maximum speed and won't slow down.
- However, I found a way to make it slow down. I suspend my session (by
clicking on the "suspend" button when logging off from the K menu) and when I
turn the laptop on again, the fan is at a normal speed and it looks like it
won't go crazy again. The drawback is that after resuming there is always a
process consuming about 20% of cpu power, kacpid, here is it's line copied from
"top":

processes consuming about 25% of cpu power, kacpid and kacpi_notify. Here are
the lines concerning those processes copied from "top":
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
- 31 root 11 -5 0 0 0 S 19.7 0.0 9:37.50 kacpid
+ 31 root 11 -5 0 0 0 S 19.4 0.0 6:41.12 kacpid
+ 32 root 10 -5 0 0 0 S 6.6 0.0 2:13.26 kacpi_notify
Thank you and sorry because I really don't know to which package this
bug should be assigned... The kernel maybe ?
