All,
This is just a heads-up that the new C7 update kernel breaks ABI
compatibility, at least as far as using the ELrepo nVidia drivers is
concerned. I have posted more details to the ELrepo list; but since many
folks use the Elrepo kmods I thought a heads-up would be appropriate.
If you use the ELrepo nvidia kmod you will either need to hold off on the
kernel update or uninstall the nvidia kmod.
This is being tracked here:
https://elrepo.org/bugs/view.php?id=720
didn't we just go thru this a few months ago? they're breaking it again?
It's not uncommon for bits (non kABI whitelisted bits) of the kernel ABI
to change at point releases, but in my experience it's very uncommon for
the ABI to change within a point release series. To the best of my
knowledge I recall it happening twice before on the EL6 kernel, once
such example was here:
http://elrepo.org/bugs/view.php?id=406
Of course any kABI changes will only affect 3rd party kernel modules
using those specific ABIs so the vast majority of users will be
oblivious to the changes. It just so happens in this case it affected
the 3rd party nvidia drivers which are widely used.
