Re: 2.6.27-rc1: critical thermal shutdown on thinkpad x60

Hi!

Aug 6 11:00:10 amd kernel: ACPI: Critical trip point
Aug 6 11:00:10 amd kernel: Critical temperature reached (128 C),
shutting down.
Aug 6 11:00:10 amd shutdown[24414]: shutting down for system halt

...and machine went down at that point :-(.

This one is quite repeatable:

Aug 7 10:46:24 amd dhclient: DHCPACK from 10.20.0.2
Aug 7 10:46:24 amd dhclient: bound to 10.20.5.28 -- renewal in 7200
seconds.
Aug 7 10:50:46 amd kernel: thinkpad_acpi: unhandled HKEY event 0x6022
Aug 7 10:51:03 amd last message repeated 48 times
Aug 7 10:51:05 amd kernel: ACPI: Critical trip point
Aug 7 10:51:05 amd kernel: Critical temperature reached (128 C),
shutting down.
Aug 7 10:51:05 amd shutdown[1928]: shutting down for system halt
Aug 7 10:51:06 amd init: Switching to runlevel: 0
Aug 7 10:51:06 amd kernel: thinkpad_acpi: unhandled HKEY event 0x6022
Aug 7 10:51:09 amd last message repeated 7 times
Aug 7 10:51:09 amd kernel: ACPI: Critical trip point
Aug 7 10:51:09 amd kernel: Critical temperature reached (128 C),
shutting down.
Aug 7 10:51:12 amd exiting on signal 15
Aug 7 10:54:01 amd syslogd 1.5.0#1: restart.
Aug 7 10:54:01 amd kernel: klogd 1.5.0#1, log source = /proc/kmsg
started.

...and it does not seem to be stray reading from the sensor: cat
/proc/acpi/therm*/*/* shows the bogus value in like 5 consecutive
readings.

Plus the temperature rises up to 95C before this triggers, and machine
is so hot it refuses to start again. Trip points seem to assume 128C,
too:

root@amd:~# cat /proc/acpi/thermal_zone/THM*/trip*
critical (S5): 127 C
critical (S5): 97 C
passive: 93 C: tc1=5 tc2=4 tsp=600 devices=CPU0 CPU1
root@amd:~#
