Some kernel modules take substantial time to initialize. For example, with mpt2sas RAID driver inspection and deployment randomly fail due to IPA starting before the driver finishes initialization. As much as I hate it, the only way to guarantee that the hardware is truely initalized is to wait for it. Apparently all hardware in Linux is treated as hotplugged, so there is no such thing as "hardware initialization is finished". Operators can add a sleep based on their knowledge of their hardware. The default behaviour remains the same. Change-Id: I0446ae81d760dacaf31eea6ad9f9eaa098cf5e93 Partial-Bug: #1582797
