Tomorrow, I boot my PC on 3.13.0.142 kernel. There was lots of updates for several compiler.
Right after I reboot my PC and go to the -143 kernel. dkms remove nvidia, dkms install nvidia. then, modinfo nvidia| grep vermagic now shoes "retpoline". At this point I know everything was fixed. Reboot the PC, load -143 kernel. It works. Finally. Doest it mean the -143 kernel was compiled with different version of gcc that default 14.04 gcc? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750937 Title: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04) by an insufficient compiler!
