    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:~#
