Don't bind to the device in that case, so that we > don't report this bogus value to userspace. 36.5°C might be a legitimate value - for instance, if the driver is loaded after a cold boot in a temperature-controlled machine room, the properly cooled chipset might not have reached 37°C yet, so the chip will legitimately report 0x7F in TSFSC... I _think_ a safer way would be to check variability - if it's not 0x7F then fine, it's likely working. If is is, then drop TSTHRTHI by ~30°C ; if TSFSC still reports 0x7F then it's definitely wrong since that would be 6.5°C (machine room in the [ant]arctic where that would still be legit shouldn't worry about chipset temperature anyway :-) OTOH, just loading the driver a couple of minutes after boot would work with your current test.
