Output of 'dmesg' on Kernel 6.8
Hi, I have a Framework 13 AMD, which had 4 detected thermal zones though ACPI,
but starting with kernel 6.8 they no longer appear and the following gets
printed in dmesg:
```
[ 0.630727] ACPI: thermal: [Firmware Bug]: Invalid critical threshold
(-274000)
[ 0.630738] ACPI: thermal: [Firmware Bug]: No valid trip points!
[ 0.630819] ACPI: thermal: [Firmware Bug]: Invalid critical threshold
(-274000)
[ 0.630828] ACPI: thermal: [Firmware Bug]: No valid trip points!
[ 0.630904] ACPI: thermal: [Firmware Bug]: Invalid critical threshold
(-274000)
[ 0.630913] ACPI: thermal: [Firmware Bug]: No valid trip points!
[ 0.630991] ACPI: thermal: [Firmware Bug]: Invalid critical threshold
(-274000)
[ 0.631000] ACPI: thermal: [Firmware Bug]: No valid trip points!
```
for comparison this is 6.7.9:
```
[ 0.632366] ACPI: thermal: Thermal Zone [TZ00] (42 C)
[ 0.632593] ACPI: thermal: Thermal Zone [TZ01] (41 C)
[ 0.632773] ACPI: thermal: Thermal Zone [TZ02] (39 C)
[ 0.632867] ACPI: thermal: Thermal Zone [TZ03] (57 C)
```
Thanks,
Steve
