Hello everyone, I have just read in kernel change log that errors like the one I've been encountering are to be reported here, so here goes: my Dell Latitude D810 laptop (with a Pentium III M processor) occasionally trips on its ACPI critical thermal trip point despite never actually reaching that temperature. There is a single thermal trip point defined on this laptop, a critical S5 set to 101 Celsius. Once in a while the system hits that trip point and shuts down, despite the fact that temperature monitors (both ACPI and the I8K one) have never, ever shown it go above 70 Celsius. Frequency of such trips appears to be correlated to the laptop's temperature, with trips happening more often when the system runs hotter - then again, I have even seen it trip while only around 40 Celsius! CONFIG_HWMON is not set in kernel configuration so it doesn't seem to be a conflict between sensors and ACPI. Last but not least, in the pre-2.6.23 days, when it was still possible to change the trip point thresholds by writing to /proc/acpi/thermal_zone/*/trip_points, I raised that one from 101 to 105 degrees and it seemed to help; unfortunately this feature no longer seems to be available in more modern kernels. For your information, I have seen this problem in each stable kernel version I've used - from 2.6.20 to the latest 2.6.24 inclusive. ACPI is compiled into the main kernel. Should you need any more information, please let me know. PS. Is there any way of raising the trip point threshold in 2.6.23 and up? There is thermal.nocrt of course but I wouldn't want to entirely disable the trip - especially given it's the only one this laptop has.
