[Ubuntu-x-swat] [Bug 1750937] Re: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04)

2018-02-23 Thread Tim Habigt
Yes, I also got the gcc update after the kernel update. With the new
gcc, I could fix the Nvidia kernel module.

Here's how:
# Show the current vermagic string of the kernel module
modinfo nvidia-384 -k 4.4.0-116-generic

# It will probably say:
# vermagic:   4.4.0-116-generic SMP mod_unload modversions
# Here the retpoline string is missing.
# You can fix this by removing and re-building the module with DKMS

sudo dkms remove nvidia-384/384.111 -k 4.4.0-116-generic
sudo dkms install nvidia-384/384.111 -k 4.4.0-116-generic

# After that the modinfo command will show
# vermagic:   4.4.0-116-generic SMP mod_unload modversions retpoline

You can now use the new kernel. You will probably have to do this with
all your DKMS kernel modules.

It seems to me that all modules that were re-built with DKMS are
affected by this. For example, I get the same error message when I try
to load the "vboxdrv" module from VirtualBox.
