Hello,
When it happens, sensors indicates a temperature of 0°C for every CPU. The fan stops working and the PC is getting hot. At that point, it seems safer to shutdown the computer ... If I restart it reboots normally and the fan is on, sensors indicates above 50°C ... This seems to happen after several log in/out of different users.
I have just updated the PC and I now use "xf86-video-ati" instead of "catalyst". I have always been annoyed by xf86-video-ati because the fan is mostly always on when I use this driver (maybe there is a setting I should change somewhere)
Any idea what could go wrong ? (Dell XPS Studio with a Radeon HD 4670)
Thanks

I have this sometimes on my lenovo. I think I've connected my problem to too much moisture.
The solution for me is the standard operation procedure. Strike a good punch at the fan area and it starts up again.

I have HD3200 graphics in my laptop and ati runs around 6C hotter than fglrx.
What does "acpi -ti" show before and after the temp indicates 0C?
I can also do
$ cat /proc/acpi/thermal_zone/CPUZ/*
<setting not supported>
polling frequency: 3 seconds
state: ok
temperature: 48 C
critical (S5): 105 C
passive: 100 C: tc1=1 tc2=2 tsp=100 devices=CPU0 CPU1
active[0]: 85 C: devices=FAN0
active[1]: 70 C: devices=FAN1
active[2]: 62 C: devices=FAN2
active[3]: 45 C: devices=FAN3
$ cat /proc/acpi/fan/FAN*/state
