PROBLEM:  (QAR 70481)    (Patch ID: OSF425-614)
********
This patch fixes a system panic during dynamic configuration of device
drivers.  If more than one adapter for that device driver exists in the
system and if one of those adapters fails the configuration, the device
driver gets unloaded. The adapter still uses the device driver code causing
the system to panic with an invalid instruction fetch.

have an incorrect mapping.
