Nic lost with new kernel

Postby northernsky » 2017/11/14 17:01:58

Hello,

Ever since I upgraded from 3.10.0-514.26.2.e17.x86_64 to 3.10.0-693.2.2(and recently 693.5.2) my NIC drivers are gone. I have tried looking for them with NIC manager but they do not exists with the 693 versions. I have to keep reverting back to the last 514 version t be able to work with my Centos 7 os. I am by no means a Linux pro and am asking is anyone can point me in the right direction to get this working so I do not fall so behind in updates and I do not want to re-install again if I do not have to.

thanks,

Scott

Post the output from lspci -nn | grep -i net so we can see what network card you have and which driver it would use.

You need to update your version of kmod-forcedeth from ELRepo then. If you downloaded just kmod-forcedeth from them to start with and did not install the elrepo-release package then the repo will not exist on your system. If you did install it but subsequently disabled it then re-enable it (edit /etc/yum.repos.d/elrepo.repo and change enabled=0 to 1). If it's not installed then download it and install it. With the repo enabled, when you update the kernel it will download the newer kmod-forcedeth and update it at the same time.

The newer kmod is required as RH changed the kernel ABI with the point release kernel and the package had to be rebuilt. It should now work for all of 7.4 and hopefully future point releases unless RH change the ABI again (which they usually only do at point releases).

Hello Treverh,

Ok so after some trial and error I downloaded kmod-forcedeth-0.64-3.el7.elrepo.x86_64.rpm and my 693.5.2 kernel is working now. I wanted to ask one more question. How do you delete the kernels from the older list that shows up when you reboot?

Thanks,

Scott

Actually nm I just searched and found one of your older posts telling someone else how to yum remove kernel-3.yaddayadda.

thanks again for your help!
