Local fix
Problem summary
As the hardware implementation doesn't have a semaphore mechanism, concurrent access to the I2C bus may result in adapter reset failure, which inturn cause a FW Dump.
Problem conclusion
Qlogic introduced a shared RISC-to-RISC semaphore to indicate shared I2C accesses are occuring. Before resetting the ISP the driver must acquire the shared semaphore, within the stipulated time mentioned by the Qlogic documentaiton. This will avoid the access contention for I2C Bus.
Temporary fix
