When I take the laptop off ac I get an immediate thermal shutdown from zone 2 going critical. I traced temp readings and see the following: acpi_tz0: newflags 0, temp 56.0 @ ticks 10080 acpi_tz1: newflags 0, temp 49.0 @ ticks 10081 acpi_tz2: newflags 0, temp 26.6 @ ticks 10088 acpi_tz0: newflags 0, temp 53.0 @ ticks 20096 acpi_tz1: newflags 0, temp 49.0 @ ticks 20105 acpi_tz2: newflags 0, temp 26.6 @ ticks 20114 acpi_tz0: newflags 0, temp 52.0 @ ticks 30123 acpi_tz1: newflags 0, temp 49.0 @ ticks 30132 acpi_tz2: newflags 0, temp 26.6 @ ticks 30141 acpi_tz0: newflags 0, temp 51.0 @ ticks 35148 acpi_tz0: newflags 0, temp 51.0 @ ticks 35185 acpi_tz1: newflags 0, temp 49.0 @ ticks 35194 acpi_tz1: newflags 0, temp 49.0 @ ticks 35209 acpi_tz2: newflags 0, temp 26.6 @ ticks 35219 acpi_tz0: newflags 0, temp 51.0 @ ticks 45229 acpi_tz1: newflags 0, temp 48.0 @ ticks 45238 acpi_tz2: newflags 9, temp 152.1 @ ticks 45247 acpi_tz0: newflags 0, temp 50.0 @ ticks 55256 acpi_tz1: newflags 0, temp 48.0 @ ticks 55265 acpi_tz2: newflags 9, temp 152.1 @ ticks 55273 acpi_tz0: newflags 0, temp 50.0 @ ticks 65283 acpi_tz1: newflags 0, temp 48.0 @ ticks 65293 acpi_tz2: newflags 9, temp 152.1 @ ticks 65301 acpi_tz2: WARNING - current temperature (152.1C) exceeds safe limits This condition persists if I disable the shutdown call in acpi_thermal.c. Once returned to ac the zone immediately returns to <30C. I felt around for a hotspot but cannot find one so figure this may be an acpi issue? I checked the mailing list archives and found almost an identical complaint for an nc6230: http://monkey.org/freebsd/archive/freebsd-acpi/200509/msg00071.html I've stuck dmesg (w/ debug printfs) and output from acpidump -t -d on the web: http://people.freebsd.org/~sam/nx6125.dmesg http://people.freebsd.org/~sam/nx6125.acpidump Any suggestions on what to look for? FWIW the fan in zone 0 does seem to kick in a fair amount even when the system is idle. Sam
