一台PowerEdge R710在升级intel i350网卡固件的时候，出现如下错误：

Executing update...

WARNING: DO NOT STOP THIS PROCESS OR INSTALL OTHER DELL PRODUCTS WHILE UPDATE IS IN PROGRESS.

THESE ACTIONS MAY CAUSE YOUR SYSTEM TO BECOME UNSTABLE!

.....UpdateDevice Error: 6 [Tool failed with code 1792]

UpdateDevice Error: 6 [Tool failed with code 1792]

UpdateDevice Error: 6 [Tool failed with code 1792]

UpdateDevice Error: 6 [Tool failed with code 1792]

.

Device: Intel(R) Gigabit 4P I350-t rNDC

  Application: Intel(R) Gigabit 4P I350-t rNDC

  Update Failed [Tool failed with code 1792].

 

然后启动就发现网卡驱动无法加载了，网卡也就用不起了。
dmesg的时候提示：

The NVM Checksum Is Not Valid
 
找到一个Workaround：

下载igb驱动源码，将igb-5.1.2.tar.gz 解开，修改src/igb_main.c中的内容

将下面这段注释掉：

/* make sure the NVM is good */

/*

if (e1000_validate_nvm_checksum(hw) < 0) {

    dev_err(pci_dev_to_dev(pdev), "The NVM Checksum Is Not"

    " Valid\n");

    err = -EIO;

    goto err_eeprom;

}

*/

 

然后重新打包成 igb-5.1.2.tar.gz。然后编译

rpmbuild -tb igb-5.1.2.tar.gz

然后安装编译号的rpm包。

然后   rmmod igb ，再   modprobe igb 即可正常加载驱动。
