[ Upstream commit b46ba47d7bb461a0969317be1f2e165c0571d6c5 ]
There's at least one drive (MaxDigitalData OOS14000G) such that if it receives a large amount of I/O while entering an idle power state will first exit idle before responding, including causing SMART temperature requests to be delayed.
This causes the drivetemp request to exceed its timeout of 1 second.
