Here's what i got so far:

[ 50.289736] Critical temperature reached (255 C), shutting down.
so in acpi_thermal_get_temperature() called in acpi_thermal_add() the
tz->temperature thingy is not set properly (printk's added):
[ 50.276607] Old temp: 4294967023
[ 50.281890] Got temp: 255
[ 50.282567] Old temp: 255
[ 50.287882] Got temp: 255
What's also strange is that the tz acpi_thermal is alloc'd with kzalloc and
there's still garbage in it after reading it in acpi_thermal_get_temperature()
for the first time. Debugging continues...
