xosview2 started showing a constant value for TZ6 on an intel lenovo
laptop. It turns out to be from

$ cat /sys/class/thermal/thermal_zone6/temp
20000

$ cat /sys/class/thermal/thermal_zone6/type
INT3400 Thermal

Is this because some cooling component has failed in the mobo?

$ cat /sys/class/thermal/thermal_zone6/type
user_space step_wise bang_bang fair_share

lsmod indicates the acpi driver is being used

$ lsmod|grep thermal
int3400_thermal 20480 0
x86_pkg_temp_thermal 20480 0
processor_thermal_device 24576 0
acpi_thermal_rel 16384 1 int3400_thermal
intel_soc_dts_iosf 20480 1 processor_thermal_device
intel_rapl_common 24576 2 intel_rapl_msr,processor_thermal_device intel_pch_thermal 16384 0
int3403_thermal 20480 0
int340x_thermal_zone 16384 2 int3403_thermal,processor_thermal_device

however again the the values seem busted

$ cat /sys/devices/platform/INT3400:00/uuids/available_uuids
UNKNOWN

$cat /sys/devices/platform/INT3400:00/uuids/current_uuid
INVALID

Any ideas on how to interpret this data and deduce what is going on?
google seems to be utterly useless for this purpose. I've not been able
to find what INT3400 Thermal on google and the linux/src/Documentation.
But one bugzilla.kernel.org report suggests it is bogus (show_bug.cgi?id=205365)
