> So, please try hack thermal.c by removing calls to _TMP. I did something like that before, by changing acpi_evaluate_integer() to return 3000 if it is asked for _TMP.

If acpi_thermal_get_temperature() returns with a failure, then most of the later methods in THM0 aren't executed, so one is actually commenting out much more than _TMP. Which is why I think the minimal change is the diff above to utils.c. With that change the system never hung. Or should I do a compromise modification, where calls from thermal.c to _TMP use the hacked acpi_evaluate_integer() [e.g. acpi_evaluate_integer_called_from_thermal()], but other calls to _TMP get the unhacked version? Here is the diff for commenting out _TMP directly in thermal.c, which I think I've tried already but I'll try it again. I'm sure it'll work, though. --- a/thermal.c 2006-03-16 09:45:30.000000000 -0500 +++ b/thermal.c 2006-03-17 09:00:30.000000000 -0500 @@ -222,7 +222,7 @@ static int acpi_thermal_get_temperature( ACPI_FUNCTION_TRACE("acpi_thermal_get_temperature"); - if (!tz) + if (!tz || strcmp(tz->handle, "_TMP") == 0) return_VALUE(-EINVAL); tz->last_temperature = tz->temperature; - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
