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。
