| Doc Text: |
A call to the HP_GETHOSTINFO ioctl (I/O Control) in the mptctl module could result in the MPT (Message Passing Technology) fusion driver being reset due to erroneous detection of completed ioctl commands. With this update, the message context sent to the mptctl module is stored (previously, it was zeroed). When an ioctl command completes, the saved message context is used to recognize the completion of the message, thus resolving the faulty detection.
