"thermal.nocrt=1" will disable the actual shutdown -- but you'll still get the warning -- which might be helpful. "thermal.crt=105" would override all critical trip points to be 105, for example, but otherwise not change any behaviour. > I've done some attempts at bisecting it, but for most of the 2.6.32-rc > series the system crashes during boot in ACPI code with a backtrace > longer than the screen can display. Hmm, I don't have a T500, but I've not seen such crashes during -rc. Please send along your .config Do you still get them when disabling the thinkpad-acpi driver? Probably the most interesting place to bisect is drivers/acpi/ec.c If you can send along the dmesg from the recent failing kernel, plus the output from "grep . /proc/acpi/thermal_zone/*/*" that may be helpful. thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
