I'm seeing the same thing here, on a similar machine ( 6459CTO ). I
pulled the source from kernel git last night to test it.

I've udpated the BIOS on my T61 to 1.26 to match yours, but
running 2.6.24-rc5 I don't see the issue you reported.

If it still fails for you, please send me your .config

thanks,

Subject: ACPI : Delete the IRQ operation in throttling controll via PTC
>From : Zhao Yakui <yakui.zhao@intel.com>

The IRQ operation(enable/disable) should be avoided when throttling is
controlled via PTC method. It is replaced by the migration of task.

Applied to ACPI tree.

Linus,
I reproduced this issue on my T61, and saw it go away w/ this patch.
I'll be sending you a pull request probably Sunday night w/ this

thanks,
-Len
