I hope you can easily reproduce it?

So it's new in 2.6.27rc1 and wasn't in 2.6.26? Can you please
Yes, I'm very sure. It makes machine basically unusable.
Does this mean you can easily reproduce it?
Please do a bisect then.

Not that one :-(. Thinkpad does not even have fan device: it is
controlled by hardware.
Hi,
I see exactly the same on my x60s, but during upgrade to 2.6.26.2.

Are you sure?

yes. maybe some userspace tool controlling frequency is involved, no idea yet.
But it is 2.6.26 tree for sure.

So it definitely is in 2.6.26.2, and it definitely is in 2.6.26?

...because I'm using 2.6.26, and see nothing..

Now, the CPU cores remains on 1.67GHz and fan is unable to cool them properly
under heavy load (even if I set "level disengaged" through thinkpad fan control,
temperature sensor shows after a while 128 C (probably not real temp,
I expect some critical flag => and it properly switch off the
system...)

How do you control fans? I could not get anything but -EINVAL from IBM
ACPI driver :-(.

you need add fan_control=1 to thinkpad_acpi module

Thanks for pointers!
