Symptoms

During boot up, there is a possibility that the primary key can cause the key logic to create a new key, thus making the partition unreachable.

Impact

Once a new key is generated, the existing encryptions no longer can be decrypted and the partitions in particular become unreachable because of this condition.

Conditions

The normal state of the primary key is to not change unless there is an error in reading the key incorrectly. Attempting multiple reboots where there is a possibility of interruption with the key storage access can cause the key logic to create a new key.

Workaround

N/A

Fix Information

The retry logic was enhanced and no longer creates a new key based on recourses being temporarily unavailable.
