Re: [ibm-acpi-devel] Avoid critical temp shutdowns on specific ThinkPad T4x(p) and R50p

I'm wondering if this thread is about something similar to a problem I've seen. My T61p often locks up when the outside temperature is high or when it is humid, and the CPU temperature is high (but less than 85C). Is this like the symptom you're addressing? --

[ibm-acpi-devel] how to get OSD without tpb?

I've been playing around with the new input-event support in thinkpad-acpi, and by and large it works well. (I'm using a T60p, Debian unstable, linux 2.6.22.1 with thinkpad-acpi 0.15-20070714.) I seem to be getting most of the input events I expect However, when I disable tpb, although all th
