Description Kai-Heng Feng 2021-03-24 07:10:18 UTC 
On some laptops, the root port for Intel XMM7360 WWAN supports D3cold.

When the root port is put to D3cold by system suspend or runtime suspend, the system/runtime resume will freeze the laptop.
Comment 1 Kai-Heng Feng 2021-03-24 07:10:57 UTC 
After the freeze, the laptop will automatically shutdown.
