I was able to locate the related portion of the driver code, but have found no solution as of yet.

line 320:

default:
dev_err(&drv_data->adapter.dev,
"mv64xxx_i2c_fsm: Ctlr Error -- state: 0x%x, "
"status: 0x%x, addr: 0x%x, flags: 0x%x\n",
drv_data->state, status, drv_data->msg->addr,
drv_data->msg->flags);
drv_data->action = MV64XXX_I2C_ACTION_SEND_STOP;
mv64xxx_i2c_hw_init(drv_data);
drv_data->rc = -EIO;
}
