I posted the acpidump here: http://people.freebsd.org/~deischen/stl2.iasl The problem is that acpi_thermal keeps shutting down the system after 2 minutes into a buildkernel. The system has no load other than the buildkernel at the time it shuts down. The system is a Intel STL2 Tupelo motherboard with 1 CPU, the other CPU socket being occupied by a CPU terminator thingy. I uncovered the rackmount system and watched it while building a kernel. With the cover off the acpi monitored temperature went to 107C and stayed there. It only took a minute or two to get there. I felt around inside the chassis and nothing was even near being to warm or hot. With the cover on, the temperature goes to 111/112C before being shutdown by acpi_thermal (the limit being 110C). There is no way anything in that chassis is anywhere near 100C. I've disabled acpi_thermal for now, but it'd be nice to get a better fix. Any ideas? -- DE
