Atom E3940 THERMTRIP_N is asserted between -5 and 5 degrees centigrade.

We have a test which executed power-on and graceful shutdown on low temperature.
But a few of E3940 asserted THERMTRIP_N and shutdown during BIOS post.
We carefully checked whether the power button was pressed and SOC_PWROK was de-asserted unexpectedly.
Unfortunately they are very well.
What can we do for this issue?
Can we disable THERMTRIP_N during BIOS post and enable it on OS?
