Hi!
On 2.6.27-rc8 on via/fic subnotebook, throttling seems to be broken. I
can do echo 15 > /proc/acpi/processor/*/throttling, and proc file
reflects new value, but cpu still runs at same speed.
It worked on opensuse11/sled10 kernels at least...
Pavel

Any chance to check 2.6.26.x on that?
Thanks,
Rafael

After echo 15 > /proc/acpi/processor/*/throttling, what T-state is
displayed by cat /proc/acpi/processor/*/throttling?
If you do the above test on the 2.6.26.x kernel, what T-state is
displayed ?
Thanks.

IIRC that worked correctly. I.e. "*" moved to T15.

Throttling seems to work there and T15 is correctly marked by "*".

2.6.26 seems to be okay, and my thinkpad seems to be okay, too...
