------- Additional Comments From [EMAIL PROTECTED] 2006-03-25 01:02 ------- I can still reproduce the problem. A description of my kernel can be found at http://www.ceiriog.eclipse.co.uk/2.6.16-prw7 My kernel configuration (.config) can be found at http://www.ceiriog.eclipse.co.uk/dot-config-2.6.16-prw7 Additional patches mentioned in the kernel description can be found at http://gaugusch.at/acpi-dsdt-initrd-patches/acpi-dsdt-initrd-v0.7e-2.6.14.patch http://www.suspend2.net/ and in the directory http://www.ceiriog.eclipse.co.uk/patches I find that full ACPI debugging gives me too much information, so I have prepared a small patch which will show you the flow of control http://www.ceiriog.eclipse.co.uk/patches/acpi_events.patch In order to reproduce the problem reliably you need to turn thermal zone polling OFF with echo 0 > /proc/acpi/thermal_zone/TZ1/polling_frequency. You also need to turn off any application which is reading the temperature /proc/acpi/thermal_zone/TZ1/temperature. You might also want to enable some limited ACPI debugging with echo 0x0f > /proc/acpi/debug_level. Then run a CPU-intensive application (glxgears will do it eventually, so will a kernel compilation). You may monitor the temperature using watch "cat /proc/acpi/thermal_zone/*/temperature", but kill this process just before the temperature reaches 65C. Wait a while until you are confident that the temperature has exceeded 65C. Then do "acpi -t" or "cat /proc/acpi/thermal_zone/*/temperature" and you should find (1) the system seems to hang for a fraction of a second (or several seconds if it is a long time since the trip point was exceeded) and (2) you get something in the system log like http://www.ceiriog.eclipse.co.uk/patches/messages Note how the thermal notify events Notify (\_TZ.TZ1, 0x80) are repeatedly queued and never processed until after "acpi -t" causes the evaluation of _TMP.
